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.
