How do I find my HelloAsso API credentials?

Log in to your HelloAsso account, go to **Mon Compte > Integrations & API**. You can generate your **Client ID** and **Client Secret** from the API section there.

What is an organization 'slug'?

The slug is the unique textual identifier for your association (e.g., in `helloasso.com/associations/my-asso`, the slug is `my-asso`). You can find it by using the `list_my_organizations` tool.

Can I generate a payment link directly from the AI agent?

Yes! Use the `create_checkout_intent` action. You must provide the association slug and a JSON string with the amount (in cents) and return URL. The agent will return a redirect link for the user.

Is the integration secure for association data?

Absolutely. The integration uses industry-standard OAuth 2.0 Client Credentials over HTTPS. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.

HelloAsso + Pydantic AI FAQ

Common questions about integrating HelloAsso MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your HelloAsso MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
