Little Green Light
Add Little Green Light to your product for your customers, and give your AI agents governed access to it.
Embed a Little Green Light integration so your nonprofit customers can work their own donor records inside your product instead of importing spreadsheets. Every organisation tracks constituents differently, so custom fields and categories are mapped per tenant as configuration rather than code. fastn handles per-customer authentication, token refresh, pagination and API upkeep, so an unusual setup does not need a release from you.

For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a donor's giving history before drafting an ask or thank you.
An agent creates or updates a constituent record within governed permissions, with each write audited.
An agent flags donors who gave last year but not this year, so nobody is missed.

Why teams use the Little Green Light integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Little Green Light integration without building it. Your customers connect their own Little Green Light account inside your product and work their accounts, contacts and opportunities there, with no per-customer code on your side.
- Handle the part that actually costs time: every CRM instance is customised, so standard objects are never the whole story. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Little Green Light update is not your on-call problem.
- One integration serves your product and your agents. The same governed Little Green Light connection powers in-product features and gives AI agents scoped, audited access, so you keep customer records aligned between your product and the CRM each customer already runs without wiring it twice.

Google AdsLittle Green Light integration FAQ
How do I add a Little Green Light integration to my product?
Enable the Little Green Light connector in your fastn dashboard, then let each customer authenticate their own Little Green Light account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Little Green Light client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Little Green Light account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Little Green Light account and only ever sees their own accounts, contacts and opportunities. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Little Green Light integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads a donor's giving history before drafting an ask or thank you.
Who maintains the Little Green Light integration?
fastn does. When Little Green Light changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Does the Little Green Light integration support custom fields and custom objects?
Yes. CRM instances are heavily customised, so field and object mapping is configuration rather than code. Each customer maps their own fields during setup, which means onboarding a customer with an unusual Little Green Light schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from Little Green Light, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in Little Green Light do not drift apart.
What can I build with the Little Green Light integration?
A common starting point: connect their own Little Green Light account so your product reads constituents and giving history. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Little Green Light integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Little Green Light does not change your per-connector cost. You can start free with 3 connected accounts.
