EasyCoexistence vs building it yourself

What would you actually have to build?

Less than people expect for the first version, and more than they expect for the one that holds up.

The first version is a Meta app, Embedded Signup, an endpoint that answers the verification handshake, and a send call. That is genuinely a weekend for someone comfortable with OAuth and webhooks, and our own documentation pages describe most of it.

The version that holds up is different. It handles eight webhook event types by name, distinguishes a revoked token from a removed number, polls quality rating and messaging tier because neither arrives as an event you can rely on, reapplies the webhook override after a reconnection uninstalls it, and separates a fourteen day inactivity disconnection from a customer who actually left. Each of those was learned from something breaking.

What is the part that cannot be shortcut?

Becoming your own Meta Tech Provider, which is the difference between connecting one number and connecting other people's.

It is free, and it is not quick. It needs a verified Business Manager, an app that passes App Review, and recorded videos demonstrating the flows. Until that is done you are working through somebody else's provider account, which is what produces the single connection limits people hit with off the shelf tooling.

If you are connecting one number that you own, none of this applies and you should just build it. If you are connecting numbers for clients, this is the actual project, and it is measured in weeks of waiting rather than days of work.

What does the monitoring actually cost to run?

It is the part with no completion date, which is what makes it different from the rest.

A connection fails silently. The WhatsApp Business app keeps working through a quality drop, an expired token, a removed webhook override and a fourteen day disconnection, so nothing on the phone indicates a problem and the first signal is usually a customer asking why nobody replied.

Catching that means a scheduled poller, a webhook receiver, somewhere to store state, alerting, and someone who notices the alert. None of it is hard. All of it has to keep running, and it has to keep being correct as Meta changes things, which it does. That is the honest thing being bought here rather than the API calls.
