detected celebrities and facial attributes using the amazon rekognition celebrity detection add on can be used together with the auto_tagging parameter to apply tags automatically relevant for images only auto_chaptering boolean whether to trigger automatic generation of video chapters chapters will be generated and saved as a vtt file with chapters appended to the public id of the video you can enable chapters as part of the cloudinary video player default false relevant for videos and audio files only the asset must contain an audio track and the result is empty if that audio contains no speech if you re using our asia pacific data center you currently can t request auto chaptering auto_transcription boolean or object whether to trigger automatic video transcription or a set of languages to translate the transcript to alongside the native language the transcripts get generated and saved as a transcript file with the same public id as the video and with the language code appended for the translated transcripts you can use your transcript file to show subtitles or captions using the cloudinary video player when set to an object you can include original_language string to specify the language of the video s audio as a hint for more accurate transcription and or translate array to request translated transcripts see specifying the original language default false relevant for videos and audio files only the asset must contain an audio track and only spoken words get transcribed if you re using our asia pacific data center you currently can t request auto transcription auto_video_details boolean whether to trigger automatic generation of ai generated video title description and tags the generated content includes video title and video description contextual metadata fields that the cloudinary video player version 3 1 0 can use to display video title and description information plus automatic tags for asset management cloudinary generates title and description only if no video title or video description context metadata values exist cloudinary adds any generated tags to existing tags on the asset default false relevant for videos and audio files only the asset must contain an audio track and the result is empty if that audio contains no speech not currently supported by sdks if you re using our asia pacific data center you currently can t request auto video details ocr string set to adv_ocr to extract all text elements in an image as well as the bounding box coordinates of each detected element using the ocr text detection and extraction add on relevant for images only visual_search boolean deprecated this parameter no longer has any effect once cloudinary enables visual search for your product environment it automatically indexes every image for visual search and setting this parameter to false doesn t prevent indexing there s currently no supported way to exclude an image from visual search relevant for images only exif boolean whether to retrieve the exif metadata of the uploaded photo default false deprecated use media_metadata instead manipulations eager string a list of transformations to create for the uploaded asset instead of lazily creating them when first accessed by your site s visitors see the transformation url api reference for more details on possible values this option accepts either a single transformation or a pipe separated list of transformations to create for the uploaded asset sdks supports arrays in net sdk parameter name is eagertransforms eager_async boolean whether to generate the eager transformations asynchronously in the background after the upload request is completed rather than online as part of the upload call default false eager_notification_url string an http or https url to send a notification to a webhook when the generation of eager transformations is completed transformation string an incoming transformation to run on the uploaded asset before saving it in the cloud this parameter is given as a string of comma separated single characters separated with a slash for chained transformations sdks supports a hash of transformation parameters or an array of hashes for chained transformations note when using the sdk for a dynamically typed language such as ruby the transformation parameters can be specified directly without using this transformation parameter format string an optional format to convert the uploaded asset to before saving in the cloud for example jpg note when used together with allowed_formats the format conversion only applies to files whose format is not listed in allowed_formats files whose format is listed in allowed_formats are stored as is for example if allowed_formats jpg png and format jpg uploading a png keeps it as png while uploading a gif converts it to jpg face_coordinates string relevant for images only the coordinates of faces contained in an uploaded image to override the automatically detected faces each face is specified by the x y coordinates of the top left corner and the width height of the face the coordinates for each face are given as a comma separated list with individual faces separated with a pipe for example 10 20 150 130 213 345 82 61 sdks supports arrays for example 10 20 150 130 213 345 82 61 note not relevant ignored in upload presets custom_coordinates string relevant for images only the coordinates of one or more regions contained in the image being uploaded that can be subsequently used for cropping or adding layers using the custom gravity mode specify regions by the x y coordinates of the top left corner and the width height of the region as a comma separated list for example 85 120 220 310 to specify more than one region separate them with a pipe for example 85 120 220 310 150 180 100 300 sdks supports arrays for example 85 120 220 310 note not relevant ignored in upload presets learn more regions json relevant for images only the coordinates of one or more named regions contained in the image being uploaded that can be subsequently used for cropping using the region gravity mode each region is specified by a name alphanumeric characters and hyphens permitted and an array of at least two x y coordinate pairs e g name1 1 2 3 4 name2 5 6 7 8 9 10 if two pairs are specified these refer to the top left and bottom right coordinates of a rectangle otherwise if more pairs are specified they refer to the corners of a custom region note not relevant ignored in upload presets learn more background_removal string automatically remove the background of an image set to cloudinary_ai to use cloudinary s built in deep learning based functionality note it s recommended to store the original and use background removal on the fly set to pixelz to use the human powered pixelz remove the background editing add on service note this add on is discontinued and not available for new customers relevant for images only asynchronous raw_convert string generates a related file based on the uploaded file set to aspose to automatically create a pdf or other image format from a raw office document using the aspose document conversion add on asynchronous set to google_speech to instruct the google ai video transcription add on to generate an automatic transcript raw file from an uploaded video asynchronous set to extract_text to extract all the text from a pdf file and store it in a raw json file with a public id in the format pdf_public_id extract_text json the full url of the generated json file is included in the api response unlike the above raw_convert options this option doesn t require registering for an add on synchronous see also converting raw files additional options allowed_formats string a comma separated list of file formats that are allowed for uploading files of other types will be rejected the formats can be any combination of image types video formats or raw file extensions for example mp4 ogv jpg png pdf default any supported format for images and videos and any kind of raw file i e no restrictions by default sdks supports arrays for example mp4 ogv jpg png pdf note you can also add the format parameter to convert other file types instead of rejecting them in this case only files that would normally be rejected are converted any file format allowed for upload won t be converted async boolean tells cloudinary whether to perform the upload request in the background asynchronously default false python sdk note because async is a reserved keyword in python pass it using dictionary unpacking with for example cloudinary uploader upload sample jpg async true backup boolean tell cloudinary whether to back up the uploaded asset overrides the default backup settings of your product environment callback string deprecated a url to redirect to after the upload is completed instead of returning the upload response eval string allows you to modify upload parameters by specifying custom logic with javascript this can be useful for conditionally adding tags contextual metadata structured metadata or eager transformations depending on specific criteria of the uploaded file for more details see evaluating and modifying upload parameters on_success string allows you to update an asset by specifying custom logic with javascript that is executed after the upload to cloudinary is completed successfully this can be useful for conditionally adding tags contextual metadata and structured metadata depending on the results of using the detection parameter on upload for more details see on success update script headers string an http header or a list of headers lines for adding as response http headers when delivering the asset to your users supported headers link authorization x robots tag for example x robots tag noindex sending request headers when fetching from a protected remote url when the file parameter is a remote http s url you can use the headers parameter to include request headers in the fetch cloudinary performs against the remote source this is useful when the remote asset requires authentication for example with an authorization header example node js cloudinary v2 uploader upload https example com private image jpg headers authorization basic base64 encoded username password then result console log result invalidate boolean whether to invalidate cdn cached copies of a previously uploaded asset and all transformed versions that share the same public id default false it usually takes between a few seconds and a few minutes for the invalidation to fully propagate through the cdn there are also a number of other important considerations when using the invalidate functionality moderation string for all asset types set to manual to add the uploaded asset to a list of pending assets that can be moderated using the admin api or the cloudinary console perception_point to automatically moderate the uploaded asset using the perception point malware detection add on for images only set to webpurify to automatically moderate the uploaded image using the webpurify image moderation add on aws_rek to automatically moderate the uploaded image using the amazon rekognition ai moderation add on duplicate threshold to detect if the same or a similar image already exists using the cloudinary duplicate image detection add on set threshold to a float greater than 0 and less than or equal to 1 0 to specify how similar an image needs to be in order to be considered a duplicate set threshold to 0 to add an image to the index of images that are searched when duplicate detection is invoked for another image for videos only set to aws_rek_video to automatically moderate the uploaded video using the amazon rekognition video moderation add on google_video_moderation automatically moderate the uploaded video using the google ai video moderation add on to request multiple moderations in a single api call send the desired list of moderations as a pipe separated string with manual moderation if relevant being last for example aws_rek duplicate 0 perception_point manual note rejected assets are automatically invalidated on the cdn within approximately ten minutes asynchronous notification_url string an http or https url to receive the upload response a webhook when the upload or any requested asynchronous action is completed if not specified the response is sent to the notification url if defined in the webhook notifications settings of your cloudinary console proxy string tells cloudinary to upload assets from remote urls through the given proxy format https hostname port return_delete_token boolean whether to return a deletion token in the upload response the token can be used to delete the uploaded asset within 10 minutes using an unauthenticated api request default false timeout integer sdks only add this parameter to override the maximum amount of time to wait for a response from cloudinary before the connection is terminated unsigned upload parameters you can define the following parameters directly in an unsigned upload request upload_preset public_i...
