How to Create Custom Webhook Integrations

Trigger custom workflows in Zapier, Make, n8n, or your own apps when members are approved, declined, or captured.

What are Webhooks?

Webhooks send data to a URL when events happen. Use them to:

• Add members to your CRM
• Send Slack notifications
• Trigger email sequences
• Update databases
• Create custom automations

Setup Guide

<StepGuide steps={[ { title: "Get Webhook URL", content: "From Zapier, Make, webhook.site, or your server.

Approve a test member to verify it triggers." } ]} />

Webhook Events

• member.approved - Member approved to Group
• member.declined - Member declined
• member.captured - New member request synced
• message.sent - Welcome/decline message sent
