What it does
Dropbox Sign (formerly HelloSign) sends signature requests and downloads signed PDFs. Uses api_key authentication via HTTP Basic against the legacy api.hellosign.com/v3 hostname (kept after the rebrand).
Setup
- In Dropbox Sign, open API Settings and generate an API key.
- In FlowFn, go to Platform Tools → Dropbox Sign → Connect and paste the key.
Actions
- Send Signature Request — signers + publicly-accessible file URLs + subject;
test_modedefaults to true (no email, no billing). - Get Signature Request — fetches one request and its signer status.
- Download Files — returns a time-limited URL to the combined signed PDF (or zip of source files).
Notes
test_mode defaults to true so you can ship and iterate safely; set explicitly to false for live sends. Free Dropbox Sign accounts can only API-send with test_mode: 1; live sends require a paid plan.
