What is an API integration?
An API integration is a working connection built between two software systems on top of their APIs, so data moves between them automatically instead of being retyped.
What it does for your business.
An API integration is the finished connection, not the doorway. Two systems have APIs. An integration is the working link built between them, so orders raised in your CRM appear in accounting, and payments recorded in accounting close the deal in your CRM. The business result is one version of the truth and an end to the rekeying that produces mismatched numbers. The APIs are the raw material, the integration is what someone builds, tests and then maintains.
What building one actually involves.
More than plugging in a key. Credentials and their renewal. Field mapping, deciding that your CRM company name is their customer account, and what to do when a required field is empty. Direction, meaning whether data flows one way or both, and which system wins a conflict. Rate limits, so a busy afternoon is not throttled. And error handling for the day the other side is down. The mapping conversation usually takes longer than the coding.
Integration is not a one-off export.
A CSV export is a photograph. An integration is a live link, and that difference carries an ongoing cost: vendors change their APIs, credentials expire, and edge cases surface in month three that nobody imagined in week one. Budget for monitoring and for someone to notice when a sync stops. Integrations nobody watches fail quietly, and they are usually discovered by a customer or an accountant rather than by the team that built them.
The Voltade take
We build the integrations an agent needs to do its job, and we keep the list honest: the published Gateway catalogue is what we support today. Envoy CRM connects to Plato and WESS out of the box, and anything beyond the catalogue is scoped as work rather than promised as a checkbox.
