Authentication
The REST API authenticates with bearer tokens. The MCP server uses the same tokens. Mint, manage, and revoke from the API tokens page.
Header
Authorization: Bearer your-api-token
Mint a token
- Go to API tokens.
- Click Create token, name it, pick the abilities the holder should have.
- Copy the value immediately - it's shown once.
If you lose it, revoke and mint a new one.
Test it
curl -H "Authorization: Bearer your-api-token" \
https://formspring.io/api/v1/me
You'll see your user, current team, plan, and the abilities of this token.
Plan gating
The REST API and MCP server are available on every plan, including Free. Free-plan tokens can read and write forms, submissions, links, and automations. Plan-gated resources (surveys, funnels, AI insights, custom retention) answer 402 Payment Required until the team upgrades - see Plans for the full matrix.
Revoke
Open API tokens → click the trash icon next to the token. Active sessions die on the next call.
