API workflow planning

Plan a Sendvo API workflow.

Control every record.

Software-connected mail needs more than an endpoint call. Plan the source record, send rule, duplicate key, address check, approval, campaign ID, retries, batch, and tracking join before software submits mail.

Workflow controls

Define the safety boundary first.

Six controls before production.

  • Intake

    Keep the source record visible

    Event, record ID, recipient, and timestamp.

    Event payload guidance

  • Duplicate safety

    Make repeat requests predictable

    Idempotency key, duplicate rule, retry window.

    Idempotency guidance

  • Send rule

    Separate eligibility from execution

    The rule that creates intent, and the holds.

    Send-rule guidance

  • Identity

    Use stable campaign IDs

    One ID from source record to response.

    Campaign ID guidance

  • Batch

    Define the production handoff

    An auditable batch with clear exceptions.

    Batch guidance

  • Measurement

    Join tracking without overclaiming

    Keep delivery, response, and revenue distinct.

    Measurement guidance

API guidance FAQ

Straight answers on API access.

This is workflow guidance, not a public endpoint reference. Sendvo does not publish a complete public API authentication, endpoint, request, or response contract on this website.

Plans: list upload, dedupe, and automated mail need Operator or Growth. Integrations and API access need Growth.

Is this a public Sendvo API reference?

No. This page provides workflow guidance. Sendvo does not publish a complete public endpoint and authentication reference on this website.

What should a software-connected mail workflow control?

A software-connected mail workflow should control source records, event payloads, send rules, duplicate prevention, address readiness, proof or approval state, campaign identifiers, retry behavior, batches, tracking joins, and measurement boundaries.

Does reading this page confirm API access for my account?

No. Educational guidance does not confirm account access. The authenticated Sendvo workspace shows the capabilities and plan changes available to that account.
