# Get access

Everything on the Builder Platform sits behind one OAuth 2.0 credential. There are two ways to get one, depending on what you are building.

## Path 1: your own tools and automations (most customers)

For scripts, dashboards, scheduled jobs, and internal apps, you use a **service credential** tied to your MixShift account:

1. Ask us for access ([get in touch](/contact?interest=builder-platform)) or, if your MixShift admin already has the admin page, they can mint one there directly.
2. A credential is a `client_id` and `client_secret`, shown once at mint time. Store it like any secret.
3. Exchange it for a short-lived access token whenever you need one:

```
curl -X POST https://mcp.mixshift.io/oauth/token \
  -d grant_type=client_credentials \
  -d client_id=YOUR_ID -d client_secret=YOUR_SECRET
```

4. Send `Authorization: Bearer [token]` on every call.

Credentials are read-only by default and scoped to exactly what they are allowed to see and do. Write permissions (timeline events, advertising writes, listing writes) are granted explicitly at mint time and can be revoked or rotated any time.

If the credential is for the MixShift plugin or a scheduled task rather than your own code, there is an even simpler flow where a one-time setup code does the exchange for you and no human ever handles the secret. See [Run unattended and scheduled tasks](/knowledge-base/plugin/how-to/run-unattended-and-scheduled-tasks).

## Path 2: partner software (apps acting for MixShift customers)

Building a product where MixShift customers sign in to your app? Email **support@mixshift.io** with your app name, redirect URIs, and the scopes you need. You get a registered `client_id` (plus a secret for confidential clients), and your users authorize through a standard consent screen using the authorization-code flow with PKCE.

## Trying it by hand

Want a token without writing code first? Open `mcp.mixshift.io/login?mode=direct` in a browser, sign in, and copy a token to experiment with.
