Upload a document

Upload a verification document for a customer or beneficial owner. The request must use multipart/form-data with the file in the file field and metadata in the remaining fields.

Supported file types: application/pdf, image/jpeg, and image/png. Grid matches on the Content-Type of the multipart part, not the file extension. Any other type, and any file over 10 MB, returns 400 INVALID_INPUT.

Grid forwards the file to its verification provider, which screens it as the request is handled and can reject it with 422 DOCUMENT_REJECTED. To pass that screen, a photo or scan of a document must:

  • show the whole document, with all four corners inside the frame and nothing overlapping an edge
  • be in focus and free of glare, so every field and the machine-readable zone can be read
  • be in color, not a black-and-white copy
  • be a photo or scan of the physical document, not a screen capture, and not retouched in an image editor
  • be unexpired
