CentralStationCRM
Add CentralStationCRM to your product for your customers, and give your AI agents governed access to it.
CentralStationCRM is a German SME CRM from 42he, and its API is per-tenant: every call goes to the customer's own subdomain at https://{account}.centralstationcrm.net/api, so there is no single base URL you can hard code. The key travels in an X-apikey header rather than Authorization, and each user generates their own key from My Settings, which means the API sees exactly what that user is allowed to see. Rate limiting is tight at 50 requests per 10 seconds with a 429 on breach, so bulk syncs need pacing rather than parallel fans. Notes and activities are modelled as protocols attached to people or companies, which is where most of the useful history lives, and field labels in responses are German on German accounts even where the resource names are English. A Swagger reference is published at api.centralstationcrm.net/api-docs. fastn stores each customer's subdomain and key together, paces requests inside the rate limit, and keeps the connection maintained as the API changes.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own CentralStationCRM account so contacts captured in your product appear as people against the right company.
Write activity notes back as protocols so the CRM history shows what happened in your product.
Read open deals to prioritise which accounts your product surfaces to the customer's sales team.
Keep company records in step so an address change made in either system propagates to the other.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
Let an agent log a protocol note against a person after a call, with the person, the note and the tenant recorded in a per-tenant audit trail.
Have an agent search people and companies for duplicates and propose merges without applying them.
Let an agent summarise open deals by value and report which have had no activity for a set period.

Set up CentralStationCRM in 4 steps
- 01Enable the CentralStationCRM connector from your fastn dashboard.
- 02Have each customer authorise their own CentralStationCRM account, so calls run under their credentials rather than a shared key.
- 03Decide which accounts, contacts and opportunities your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the CentralStationCRM integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a CentralStationCRM integration without building it. Your customers connect their own CentralStationCRM 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 CentralStationCRM update is not your on-call problem.
- One integration serves your product and your agents. The same governed CentralStationCRM 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 AdsCentralStationCRM integration FAQ
How do I add a CentralStationCRM integration to my product?
Enable the CentralStationCRM connector in your fastn dashboard, then let each customer authenticate their own CentralStationCRM account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no CentralStationCRM client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own CentralStationCRM account?
Yes. Every connection is scoped to the individual customer, so each authorises their own CentralStationCRM 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 CentralStationCRM integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Let an agent log a protocol note against a person after a call, with the person, the note and the tenant recorded in a per-tenant audit trail.
Who maintains the CentralStationCRM integration?
fastn does. When CentralStationCRM 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 CentralStationCRM 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 CentralStationCRM schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from CentralStationCRM, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in CentralStationCRM do not drift apart.
What can I build with the CentralStationCRM integration?
A common starting point: let a customer connect their own CentralStationCRM account so contacts captured in your product appear as people against the right company. 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 CentralStationCRM integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding CentralStationCRM does not change your per-connector cost. You can start free with 3 connected accounts.
