Request pre-signed URLs for onboarding document uploads

Use this API to request pre-signed upload URLs for supporting documents required during corporate onboarding.

Typical documents include Certificates of Incorporation, Articles of Association, and other compliance-related files.

After submitting your request, the system will generate pre-signed URLs that must be used to upload the documents externally.

You’ll need to specify the number of files you intend to upload for each document type using the field no_of_documents.

Once the request is submitted, the system will generate and return the same number of pre-signed URLs as specified in no_of_documents (provided the request is valid and error-free).

Each pre-signed URL can then be used to upload one document.

Each pre-signed URL:

Remains valid for 10 minutes

Allows one file upload (reusing it will overwrite the previous file)

Accepts files up to 20 MB in size

Accepted file formats include:

PDFs (application/pdf, pdf)

Images (e.g. PNG, JPG, JPEG)

.zip for bundles

Don't forget to include the corporate_external_reference to correctly associate the generated URLs with the relevant onboarding application.

Please refer to the Uploading Supporting Documents section for instructions on how to upload your documents using the pre-signed URLs.
