Attributes

Note

Attributes are case-sensitive and should be inside JSON for POST request, for example:

{
    "url": "https://example.com/file1.pdf"
}

Attribute	Description	Required
url	URL to the source file. 1	yes
angle	Angle in degrees. Supported values 90, 180, and 270.	no
httpusername	HTTP auth user name if required to access source url.	no
httppassword	HTTP auth password if required to access source url.	no
pages	Specify page indices as comma-separated values or ranges to process (e.g. "0, 1, 2-" or "1, 2, 3-7"). The first-page index is 0, Use "!" before a number for inverted page numbers (e.g. "!0" for the last page). If not specified, the default configuration processes all pages. The input must be in string format.	no
async	Set async to true for long processes to run in the background, API will then return a jobId which you can use with the Background Job Check endpoint to check the status of the process and retrieve the output while you can proceed with other tasks.	no

Supports publicly accessible links from any source, including Google Drive, Dropbox, and PDF.co Built-In Files Storage. To upload files via the API, check out the File Upload section. Note: If you experience intermittent Access Denied or Too Many Requests errors, please try adding cache: to enable built-in URL caching (e.g., cache:https://example.com/file1.pdf). For data security, you have the option to encrypt output files and decrypt input files. Learn more about user-controlled data encryption.

Main response codes as follows:

Code	Description
200	Success
400	Bad request. Typically happens because of bad input parameters, or because the input URLs can’t be reached, possibly due to access restrictions like needing a login or password.
401	Unauthorized
402	Not enough credits
445	Timeout error. To process large documents or files please use asynchronous mode (set the async parameter to true) and then check status using the /job/check endpoint. If a file contains many pages then specify a page range using the pages parameter. The number of pages of the document can be obtained using the /pdf/info endpoint.

Note

For more see the complete list of available response codes.
