POST /merge

PDF Merge. Combine documents into one, in the order you send them.

Combines two or more PDFs into one, in the order sent, optionally with a table of contents built from the source titles and continuous page numbering. Files are uploaded as multipart/form-data (fields file1, file2…) or referenced from previous async job results.

Authentication, rate limits, versioning and the error format are shared by every operation — see the API reference index and the error codes. One credit per successful request on the hosted API.
