Connecting Mixmax in practice

Mixmax counts its 120 requests per 60 second window per IP address and user, so several agents sharing one egress IP throttle each other even with separate tokens. The credential is a developer token in an X-API-Token header, and a number of endpoints are only available on the paid Small Business, Growth and Enterprise tiers.

Rate limits

120 requests per a 60 second window, counted per IP address and user.
Overage is HTTP 429 with a Retry-After header.
X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset report the window, the last as a UTC epoch timestamp.

Worth knowing

The token can also be passed as an apiToken query parameter, which puts the credential into URLs and any log that records them.
Tokens are shown once at creation in Settings > Integrations, so rotation means re-pasting rather than reading the old value.
Collections return 50 results by default and page with opaque cursor strings in next and previous, so page numbers cannot be resumed from.
Endpoint availability is plan-dependent, the Calls endpoints are a limited beta behind an allowlist, and the contact groups endpoints are deprecated.

Acts as the person, not as itself

Each user connects their own account. Every call carries both identities — the agent and the person it is acting for — so the agent can never reach past what that individual can already do.

Credentials never touch the agent

Tokens live in the vault and attach server-side at call time. The agent holds a session, not a secret, and revoking access does not mean rotating a key.

Every call on the record

Who asked, which agent acted, which action ran, and the verdict that let it through — one audit trail across every integration, not one per vendor.

What an agent can do

Each action is granted on its own. An agent allowed to read is not thereby allowed to write, and the scope beside each row is what the acting user must have connected for it to run at all.
