Pabbly Connect

Integrate WPsigner with Pabbly Connect to automate your document signing workflows — no coding required. Pabbly offers unlimited workflows with a one-time pricing option.

[!TIP] Pabbly Connect is a cost-effective alternative to Zapier and Make, offering one-time payment options with no task limits. If you prefer visual automation with per-operation pricing, check out Make or Zapier.

How It Works

WPsigner connects to Pabbly Connect in two directions:

Incoming: WPsigner → Webhook → Pabbly Workflow → External App
Outgoing: External App → Pabbly Workflow → WPsigner REST API

Direction	Pabbly Module	Use Case
WPsigner → Pabbly	Webhook trigger	React when documents are signed, created, etc.
Pabbly → WPsigner	API Request (Custom)	Create documents, send for signing

---

Requirements

• WPsigner 1.3.0+ (webhooks) / 1.8.0+ (REST API)
• A Pabbly Connect account
• A WPsigner API key with Full permissions (for outgoing calls)

---

Part 1: Receiving WPsigner Events (Triggers)

Step 1: Create a Pabbly Workflow

1. Log in to Pabbly Connect
2. Click Create Workflow
3. Name it (e.g., WPsigner Document Events)

Step 2: Set Up Webhook Trigger

1. For the Trigger app, select Webhook / API → Catch Hook
2. Pabbly will generate a unique Webhook URL — copy it
3. Click Capture Response to wait for the first event

Step 3: Register the Webhook in WPsigner

1. Go to WPsigner → More → Webhooks in your WordPress admin
2. Click Add Webhook
3. Fill in:
   • Name: Pabbly - Document Events
   • URL: Paste the Pabbly webhook URL
   • Events: Select the events you want (see Available Events)
   • Secret (optional): Add for HMAC signature verification
4. Click Save

Step 4: Test the Connection

1. In WPsigner, create or sign a test document
2. In Pabbly, you should see the captured payload
3. Click Save & Send Test Response

Step 5: Add Action Steps

After the trigger, add action modules:

• Google Sheets → Add Row
• Gmail → Send Email
• Slack → Send Message
• Notion → Create Page
• Discord → Send Message

---

Part 2: Calling WPsigner API (Actions)

Step 1: Generate API Credentials

1. Go to WPsigner → Settings → API Keys
2. Click Generate New Key
3. Set Permissions to Full
4. Copy the API Key and API Secret

[!CAUTION] Save the API Secret immediately — it is shown only once.

Step 2: Add API Request Action in Pabbly

1. For the Action app, select API Request (Custom)
2. Configure:

Setting	Value
Method	POST
URL	https://yoursite.com/wp-json/wpsigner/v1/documents
Headers	X-WPS-API-KEY: your_key
	X-WPS-API-SECRET: your_secret
	Content-Type: application/json
Body	See below

Step 3: Create a Document

{
  "title": "Contract for {{step1.name}}"
}

Step 4: Add a Signer

Add another API Request (Custom) action:

Setting	Value
URL	https://yoursite.com/wp-json/wpsigner/v1/documents/{{step2.id}}/signers
Body	{"name": "{{step1.name}}", "email": "{{step1.email}}", "role": "signer"}

Step 5: Send for Signing

Add a third action:

Setting	Value
URL	https://yoursite.com/wp-json/wpsigner/v1/documents/{{step2.id}}/send
Method	POST
