Partner Invitations
Onboard clients to connect their WhatsApp Business account or Facebook Page to your Zavu project via partner invitations.
Partner invitations allow you to generate links that your clients can use to connect a Meta channel to your project. When a client completes the flow, a new sender is automatically created in your project.
Channels
connectionType picks what the client connects. One invitation connects one channel; create one invitation per channel to onboard a client on several.
connectionType | What the client connects |
|---|---|
whatsapp_waba (default) | An official WhatsApp Business Account, through Meta's embedded signup |
messenger | A Facebook Page they administer. Its Messenger inbox, including Marketplace chats, is routed to Zavu |
Phone Number Options
These apply to whatsapp_waba only. A Facebook Page has no phone number, so sending phoneNumberId or allowedPhoneCountries with connectionType: "messenger" returns 400.
- Client provides their own number: The client uses their existing phone number to register for WhatsApp Business
- Pre-assign a Zavu number: You purchase a phone number from Zavu and assign it to the invitation. The client registers this number under their WhatsApp Business Account
Use Cases
- Agencies: Onboard client WhatsApp accounts without accessing their Facebook credentials
- SaaS platforms: Let customers self-service WhatsApp setup
- Resellers: Manage multiple client WhatsApp accounts under one project
- Managed services: Provision phone numbers and let clients complete the WhatsApp verification

Create an Invitation
Client provides their own number
terminalcurl -X POST https://api.zavu.dev/v1/invitations \ -H "Authorization: Bearer $ZAVUDEV_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "clientName": "Acme Corp", "clientEmail": "contact@acme.com", "expiresInDays": 14 }'
Pre-assign a Zavu phone number
First, purchase a phone number from Zavu, then create the invitation with the phoneNumberId:
terminalcurl -X POST https://api.zavu.dev/v1/invitations \ -H "Authorization: Bearer $ZAVUDEV_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "clientName": "Acme Corp", "clientEmail": "contact@acme.com", "phoneNumberId": "pn_abc123", "expiresInDays": 14 }'
When a phone number is pre-assigned, the client will see the number on the invitation page and use it during the WhatsApp registration. The verification code will be received via phone call to that number.
Connect a Facebook Page (Messenger)
terminalcurl -X POST https://api.zavu.dev/v1/invitations \ -H "Authorization: Bearer $ZAVUDEV_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "clientName": "Acme Corp", "clientEmail": "contact@acme.com", "connectionType": "messenger" }'
The client authorizes with Facebook, picks a Page they administer, and the resulting sender lands in your project with the Messenger channel enabled.
Response
JSON{ "invitation": { "id": "jh7am5bng9p3v2x1k4r8", "url": "https://dashboard.zavu.dev/invite/abc123xyz", "token": "abc123xyz", "clientName": "Acme Corp", "clientEmail": "contact@acme.com", "clientPhone": null, "phoneNumberId": null, "connectionType": "whatsapp_waba", "status": "pending", "senderId": null, "connectedAccount": null, "failureReason": null, "failedAt": null, "expiresAt": "2025-01-15T00:00:00.000Z", "viewedAt": null, "startedAt": null, "completedAt": null, "createdAt": "2025-01-01T12:00:00.000Z", "updatedAt": "2025-01-01T12:00:00.000Z" } }
Share the url with your client. They complete Meta's authorization to connect the channel. Once done, status is completed, senderId points at the new sender, and connectedAccount reports what was linked: the WhatsApp number or the Facebook Page.
Invitation Lifecycle
| Status | Description |
|---|---|
pending | Invitation created, waiting for client |
in_progress | Client started the signup flow |
completed | WhatsApp connected, sender created |
expired | Invitation expired before completion |
cancelled | Invitation was cancelled |
failed | The client started and did not finish. failureReason says why, and the same link can be retried |
List Invitations
terminalcurl https://api.zavu.dev/v1/invitations \ -H "Authorization: Bearer $ZAVUDEV_API_KEY"
Filter by status:
terminalcurl "https://api.zavu.dev/v1/invitations?status=completed" \ -H "Authorization: Bearer $ZAVUDEV_API_KEY"
Get Invitation Details
terminalcurl https://api.zavu.dev/v1/invitations/jh7am5bng9p3v2x1k4r8 \ -H "Authorization: Bearer $ZAVUDEV_API_KEY"
Cancel an Invitation
Cancel an active invitation to prevent the client from using it:
terminalcurl -X POST https://api.zavu.dev/v1/invitations/jh7am5bng9p3v2x1k4r8/cancel \ -H "Authorization: Bearer $ZAVUDEV_API_KEY"
After Completion
When a client completes the signup flow:
- A new sender is created in your project with WhatsApp enabled
- The sender's phone number is the client's registered WhatsApp number
- The invitation status changes to
completed - The
senderIdfield contains the ID of the created sender
You can then use this sender to send WhatsApp messages on behalf of your client:
terminalcurl -X POST https://api.zavu.dev/v1/messages \ -H "Authorization: Bearer $ZAVUDEV_API_KEY" \ -H "Zavu-Sender: snd_abc123" \ -H "Content-Type: application/json" \ -d '{ "to": "+14155551234", "channel": "whatsapp", "messageType": "template", "content": { "templateId": "tmpl_xyz789", "templateVariables": { "1": "John" } } }'
SDK Examples
TypeScriptimport Zavudev from '@zavudev/sdk'; const zavu = new Zavudev({ apiKey: process.env["ZAVUDEV_API_KEY"], }); // Create invitation const invitation = await zavu.invitations.create({ clientName: 'Acme Corp', clientEmail: 'contact@acme.com', expiresInDays: 14 }); console.log('Share this URL:', invitation.url); // List invitations const { items } = await zavu.invitations.list({ status: 'pending' }); // Cancel invitation await zavu.invitations.cancel(invitation.id);
Best Practices
- Set appropriate expiration: Use shorter expirations (3-7 days) for urgent onboarding
- Track client info: Include
clientNameandclientEmailfor easier management - Monitor status: Check for
expiredorcancelledinvitations and resend if needed - Webhooks: Configure webhooks on the resulting sender to receive inbound messages
