NationBuilder
Add NationBuilder to your product for your customers, and give your AI agents governed access to it.
Embed a NationBuilder integration so your customers work their own supporter database inside your product instead of exporting it. NationBuilder is the organising CRM behind campaigns, nonprofits and advocacy groups, so the records that matter are people, tags, lists, memberships, events and donations rather than a standard sales pipeline. Each customer authorises their own nation, so reads and writes run under their credentials and one organisation's supporter data never mixes with another's. Custom fields are common in NationBuilder, and they are mapped per tenant as configuration, so onboarding an organisation with an unusual setup does not need a release from you. fastn owns the auth, token refresh, rate limits and API upkeep, and the same governed connection serves your AI agents.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own nation so supporter and member records surface inside your product with no per-customer code.
Create and update people records from your product, including the tags and custom fields an organisation uses to segment its supporters.
Read events, RSVPs and donation records per tenant so your product can show an organiser what actually happened rather than a stale export.
Add or remove people from lists and tags when something happens in your product, so outreach follows real activity.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent looks up a supporter's history, tags and giving record before it drafts an answer, reading only that tenant's nation.
An agent tags and updates people records within scoped permissions, with every write attributed.
An agent reports how one organisation's event attendance and donations moved over a period, with each read audited.
Example prompt

- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the NationBuilder integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a NationBuilder integration without building it. Your customers connect their own NationBuilder 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 NationBuilder update is not your on-call problem.
- One integration serves your product and your agents. The same governed NationBuilder 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.

Microsoft TeamsNationBuilder integration FAQ
How do I add a NationBuilder integration to my product?
Enable the NationBuilder connector in your fastn dashboard, then let each customer authenticate their own NationBuilder account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no NationBuilder client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own NationBuilder account?
Yes. Every connection is scoped to the individual customer, so each authorises their own NationBuilder 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 NationBuilder 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 looks up a supporter's history, tags and giving record before it drafts an answer, reading only that tenant's nation.
Who maintains the NationBuilder integration?
fastn does. When NationBuilder 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 NationBuilder 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 NationBuilder schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from NationBuilder, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in NationBuilder do not drift apart.
What can I build with the NationBuilder integration?
A common starting point: let each customer connect their own nation so supporter and member records surface inside your product with no per-customer code. 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 NationBuilder integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding NationBuilder does not change your per-connector cost. You can start free with 3 connected accounts.
