# Accept Multi-Partner Solution Invitation

`POST /{Version}/{Solution-ID}/accept`

## Request

- Base URL: `https://graph.facebook.com`
- URL: `https://graph.facebook.com/{Version}/{Solution-ID}/accept`
- Auth: HTTP bearer

Accept an invitation to participate in a Multi-Partner Solution as a partner application.
This endpoint transitions the partner's status from NOTIFICATION_SENT to ACCEPTED,
enabling the solution to progress toward ACTIVE status once all required partners accept.


**Use Cases:**
- Accept partnership invitations for Multi-Partner Solutions
- Activate partner participation in existing solutions
- Confirm partner app's commitment to solution terms and conditions
- Enable solution workflow progression from INITIATED to ACTIVE status


**Business Logic:**
- Only invited partner apps can accept solution invitations
- Solution must be in INITIATED status to accept partnerships
- Partner status transitions from NOTIFICATION_SENT to ACCEPTED
- Solution may become ACTIVE once all required partners accept
- Acceptance creates formal partnership agreement between apps


**Rate Limiting:**
Standard Graph API rate limits apply. Use appropriate retry logic with exponential backoff.


**Validation:**
- Partner app must have received a valid solution invitation
- Solution must exist and be accessible to the partner app
- Partner app must have proper permissions and capabilities
- Acceptance request must include valid partner app identification
