For Agents

Mint OAuth 2.0 access tokens for AT&T platform APIs by calling the AT&T client-credentials token endpoint.

Quickstart

Get started with AT&T OAuth in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"get an AT&T access token"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with AT&T OAuth API.

Obtain a fresh OAuth 2.0 access token via POST /oauth/v4/token using client credentials

Refresh access tokens before expiry to keep AT&T platform calls authenticated

Issue per-scope tokens for downstream AT&T APIs that require scoped credentials

Centralise AT&T platform authentication for an agent that fans out to multiple AT&T services

Use for: Get a fresh AT&T access token using client credentials, Refresh an expired AT&T access token, Retrieve a scoped token for a specific AT&T platform API, Check whether an AT&T client id and secret are valid

Not supported: Does not handle SMS, voice, billing, or downstream AT&T platform APIs — use for issuing and refreshing OAuth 2.0 access tokens only.

The AT&T OAuth API is the token endpoint for the AT&T developer platform. It implements the OAuth 2.0 client-credentials flow at /oauth/v4/token, returning the access tokens that other AT&T platform APIs require for authentication. Although the API itself has a single operation, that operation is the gating step for any AT&T platform integration — without it, downstream AT&T services cannot be called.

★ Token Issuance for AT&T Platform Integrations

Any service calling AT&T platform APIs needs an OAuth 2.0 access token before it can issue requests. The AT&T OAuth API's POST /oauth/v4/token implements client-credentials issuance, returning a bearer token tied to the requested scopes. An agent then uses that token in the Authorization header for downstream AT&T calls. Token issuance and refresh logic stays isolated in this single endpoint.

POST to /oauth/v4/token with grant_type=client_credentials, client_id and client_secret, and capture the returned access_token and expires_in

Scheduled Token Refresh

Long-running AT&T integrations need to refresh tokens before expiry to avoid 401 retries. A scheduler agent calls /oauth/v4/token on a cadence shorter than expires_in, caches the latest token, and rotates it into the downstream AT&T API client. This prevents window-edge auth failures during high-volume operations.

Run a scheduled task that requests a new token at expires_in / 2 and updates the cached value used by downstream AT&T API clients

AT&T Token Management via Jentic

Through Jentic, an AI agent calling an AT&T platform API never handles the OAuth client_id or client_secret directly. Jentic stores both in the encrypted vault, calls /oauth/v4/token on demand, and injects the resulting bearer token into downstream AT&T API requests. This collapses AT&T auth into a single Jentic configuration step.

Use Jentic to search 'get an AT&T access token', load POST /oauth/v4/token, and execute with the configured client credentials to retrieve a bearer token

DESCRIPTION

POST

/oauth/v4/token

Obtain or refresh an AT&T platform OAuth 2.0 access token

POST

/oauth/v4/token

Obtain or refresh an AT&T platform OAuth 2.0 access token

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

AT&T client_id and client_secret are stored encrypted in the Jentic vault (MAXsystem). Jentic calls /oauth/v4/token on demand and injects the resulting bearer token into downstream AT&T API requests, so the agent never sees either credential.

Intent-based discovery

Agents search Jentic by intent (e.g. 'get an AT&T access token') and Jentic returns the POST /oauth/v4/token operation with its grant-type and client-credentials parameters, so the call shape is correct on the first try.

Time to first call

Direct integration: a few hours to wire the client-credentials flow, caching, and refresh. Through Jentic: a few minutes — Jentic handles issuance and rotation as part of the AT&T API call.

FAQs

Specific to using AT&T OAuth API through Jentic.

What authentication does the AT&T OAuth API use?

The AT&T OAuth API itself implements the OAuth 2.0 client-credentials flow — callers pass client_id and client_secret to POST /oauth/v4/token. Through Jentic, both credentials are held in the encrypted vault and the call is made on the agent's behalf, so the secret never enters the agent's context.

Can I refresh an AT&T access token with this API?

Yes. POST /oauth/v4/token supports the OAuth 2.0 token endpoint behaviour, including issuing a fresh access token with the client-credentials grant. Long-running clients re-call this endpoint before expires_in elapses to maintain valid tokens.

What are the rate limits for the AT&T OAuth API?

AT&T throttles token-endpoint calls per client. The spec does not encode a numeric limit — the practical guidance is to refresh tokens at half the expires_in interval and avoid issuing a new token for every downstream call by caching the most recent valid token.

How do I get an AT&T access token through Jentic?

Search Jentic for 'get an AT&T access token', load POST /oauth/v4/token, and execute. Jentic posts grant_type=client_credentials with the stored client_id and client_secret, then returns the access_token and expires_in to the agent.

Is this the only AT&T API available?

This spec covers only the OAuth token endpoint, which is the gating step for the AT&T developer platform. Other AT&T platform APIs (messaging, telco services) sit behind the same OAuth flow and consume the access tokens issued here.
