Later Influence
Connect Later Influence to pull read-only influencer marketing reports on campaign, creator, and post performance.
You paste a clientId and clientSecret that Later issues by hand for the Later Influence Reporting API. There is no self-serve console.
Partner application before this connector works
Later's own team must provision Reporting API credentials for your Later Influence instance; there is no self-serve console that issues a clientId/clientSecret.
- Typical wait
- not published
- Cost
- Not published. Later documents no separate API fee, and states no pricing or plan requirement for Reporting API access — confirm commercial terms with your Later account team.
- Blocked until approved
- Everything. The Reporting API is JWT-based: you exchange a clientId and clientSecret for a bearer token, and Later only hands those out on request, so no endpoint (instances, campaigns, platforms, creators, posts) can be called until they arrive.
- Works meanwhile
- You can read the public docs at docs.reporting.api.later.com and build/test your client against the documented request and response shapes, but no live call will authenticate.
Where to apply: Ask your Later account team, or email the contact named in the Getting Started page of docs.reporting.api.later.com with the subject line 'Reporting API access'. There is no form or developer portal.
- There is no self-serve signup — a support ticket in the general Later help centre is slower than going through your named account manager.
- This is the Later Influence (formerly Mavrck) reporting API, not the Later social scheduling product; asking the wrong team wastes days.
- Multi-instance access (aggregating several Later Influence instances) must be requested explicitly when credentials are issued.
- Later does not publish a turnaround SLA, so budget for a human email round-trip rather than same-day access.
- Setup time
- 10 min of work, plus a few business days for Later to provision the client
- Auth
- API credentials
- API base URL
- https://reporting.api.later.com/v2
- Rate limits
- 120 requests per minute per IP. Over the limit returns 429, and every response carries X-Ratelimit-Limit and X-Ratelimit-Window headers.
Before you begin
- A Later Influence subscription, formerly Mavrck. The Reporting API does not exist for Later Social scheduling plans
- A named Later account manager or CSM to raise the request with
- Reporting API access enabled on your contract. Credentials are issued manually, not generated in-app
- Read-only expectations. The API reports on campaigns, creators and posts and cannot publish or schedule
Get your credentials
Check that you are on Later Influence
Later's only public API is the read-only Later Influence Reporting API, which returns campaign, creator and post analytics. Confirm your plan with your account team before going further.
Ask Later for Reporting API access
Email your Later account team, or urvash.chheda@later.com, with the subject Reporting API access. Later provisions an OAuth client by hand and sends back a clientId and a clientSecret.
Getting started
Query influencer campaign, creator and post performance from your own systems.
- clientId
- lat_cid_****7b19
- clientSecret
- lat_sec_****c204
- Instances
- 3 workspaces
No button anywhere in the Later app mints these values.
Name every instance the client should cover
Tell Later which instances, meaning your Later Influence workspaces, PopMCP should read. List all of them in the same email.
Test the pair against the token endpoint
POST the clientId and clientSecret as JSON to https://reporting.api.later.com/oauth/token from a terminal. A working pair returns \{ "jwt": "..." \}.
Authentication
Exchange your client credentials for a short lived JWT.
- jwt
- eyJhbGciOi****9f2c
- Valid for
- 12 hours
- Header
- Authorization: Bearer <jwt>
| Status | Type | Meaning |
|---|---|---|
| 401 | ANL_00401 | Invalid, malformed or expired JWT |
| 403 | ANL_00403 | Client disabled, or instance outside your set |
Run this from a server or terminal. The API sends no CORS headers.
Paste the pair into PopMCP
Put the values in Client ID and Client secret, then click connect.
Connect in PopMCP
Open your workspace, choose Later Influence in the marketplace, and fill in the connect dialog:
| Field | What to enter |
|---|---|
| Connection typepreset | Later's only public API is the read-only Later Influence Reporting API. It reports on campaign/creator/post analytics; it cannot post or schedule. |
| Client IDtext | Issued by Later alongside your clientSecret. Request Reporting API access from your Later account manager or urvash.chheda@later.com. |
| Client secretsecret | The secret paired with your clientId. Stored encrypted; used server-side only to mint short-lived Bearer tokens.Encrypted with AES-256-GCM on save and never shown again. |
PopMCP verifies the credential against Later Influence immediately. On success the connection flips to Verified and its MCP tools are provisioned.
Verify it worked
PopMCP marks Later Influence as Connected and the instance list populates. The first call it makes is GET https://reporting.api.later.com/v2/instances with a freshly minted JWT.
Troubleshooting
401 with type ANL_00401
Why: The JWT is invalid, malformed or expired. Tokens last 12 hours.
Fix: Re-authenticate against /oauth/token. If it fails immediately after saving, the clientId and clientSecret pair is wrong, so ask Later to re-issue.
403 with type ANL_00403
Why: The credentials are valid but the client is disabled, has no accessible instances, or you asked for an instance outside its set.
Fix: Contact your Later account team to enable the client or add the missing instances to it. Instances cannot be added from the Later app.
403 on /oauth/token plus a CORS policy or Failed to fetch error
Why: The call was made from a browser. The Reporting API is server-side only and sends no CORS headers.
Fix: Test with curl or a backend HTTP client. This is expected behaviour, not an outage.
429 Too Many Requests
Why: More than 120 requests from one IP in a 60-second window.
Fix: Back off exponentially. The X-Ratelimit-Limit and X-Ratelimit-Window headers on every response tell you where you stand.
You expected to schedule or publish posts
Why: The Reporting API is read-only analytics for Later Influence. Later Social scheduling has no public API.
Fix: Use the Later app for scheduling. PopMCP can only read reporting data.
