Signing Requests

Create and Send Signing Request (Atomic)

Create and immediately send a signing request in a single atomic operation. This endpoint combines the functionality of POST /signing-requests and POST /signing-requests//send.

Key Benefits:

Single API call instead of two separate requests
Validates all send requirements BEFORE creating the signing request
Atomic credit deduction - only charges if everything succeeds
Returns status: ‘sent’ immediately with first signer details
More efficient (saves 1 API call + round-trip time)

Validation:

All standard creation validations (document/template, recipients, fields)
Additional send validations:
- All signers must have first_name and valid email
- Required read-only fields must have final_value populated
- Prefilled data fields (variable_name) must have corresponding user data
- Company must have sufficient credits (≥1)

Atomicity:

If any validation fails, nothing is created
Credit is only deducted after successful creation and before email send
If email send fails after creation, signing request remains in ‘draft’ status and credit is NOT deducted

Temporary ID Pattern: For document-based creation, use temporary IDs (format: ‘temp_X’) to reference recipients before creation. The API validates all references and automatically maps temporary IDs to real UUIDs.

Rate Limit: 120 requests/minute (same as write operations)
