Adobe Sign → DocuSign Migrator

A Python toolkit for migrating library templates from Adobe Sign (Acrobat Sign) to DocuSign. It downloads templates via the Adobe Sign API, converts them to DocuSign format, and uploads them via the DocuSign API.

---

What it does

1. Authenticates with Adobe Sign via OAuth (one-time browser flow, tokens saved to .env)
2. Downloads templates — PDF, metadata, and form field definitions
3. Converts each template to a DocuSign envelopeTemplate JSON, mapping all field types, coordinates, recipient roles, and conditional field logic
4. Authenticates with DocuSign via JWT grant (one-time browser consent, then fully automated)
5. Uploads the converted template to DocuSign via the REST API

---

Prerequisites

• Python 3.10+
• An Adobe Sign OAuth app (EU2 shard) with scopes: library_read:self library_write:self user_read:self
• A DocuSign developer account with an integration key and RSA keypair

---

Setup

1. Install Python dependencies:

pip install -r requirements.txt

2. Create a .env file in the project root (never commit this):

cp .env-sample .env

Then fill in your credentials. See .env-sample for the full list of variables with descriptions. Use account-d.docusign.com and https://demo.docusign.net/restapi for sandbox; for production replace with account.docusign.com and your account's base URL (e.g. https://na3.docusign.net/restapi).

3. Authenticate with Adobe Sign (one-time):

python3 src/adobe_auth.py

Opens a browser. After authorizing, paste the redirect URL back into the terminal. Tokens are saved to .env and auto-refreshed on subsequent runs.

4. Grant consent for DocuSign (one-time per user):

python3 src/docusign_auth.py --consent

Opens a browser for the DocuSign OAuth consent screen. After approving, paste the redirect URL back into the terminal. This grants the impersonation scope required for JWT grant. After this runs once, all subsequent API calls use JWT automatically — no further browser interaction needed.

Running a migration

List available templates in Adobe Sign:

python3 src/download_templates.py list

Download templates:

python3 src/download_templates.py download                  # all templates
python3 src/download_templates.py download "Template Name" # one specific template

Downloads to downloads/<template-name>__<id>/ — one folder per template containing metadata.json, form_fields.json, documents.json, and the PDF.

Convert a downloaded template to DocuSign format:

python3 src/compose_docusign_template.py

Writes DocuSign template JSONs to migration-output/<template-name>/docusign-template.json.

Upload to DocuSign:

python3 src/upload_docusign_template.py --file migration-output/<name>/docusign-template.json

Or run the full pipeline end-to-end:

python3 src/migrate_template.py --list                      # show available templates
python3 src/migrate_template.py --template "Template Name"  # download → convert → upload
python3 src/migrate_template.py --template "Template Name" --skip-upload  # convert only

If multiple templates share the same name, the most recently modified one is used.
