The WhatsApp Business Platform lets businesses connect messaging to their own applications and customer service systems. API access alone does not provide an agent workspace or chatbot; these need to be configured separately. Setup should do more than activate a number: it should connect customer requests to the right team and information.

## Key Takeaways
- API access does not mean your agent workspace or chatbot is ready.
- Assess how your existing number is used before planning a migration.
- Test incoming messages, delivery statuses and team handover together.
- Separate platform, setup and channel fees when calculating total cost.

## What to prepare before you start

- An authorized administrator with access to the business account.
- The correct business name, contact information and verification documents where required.
- Access to the phone number you plan to use and an overview of its current WhatsApp usage.
- Questions to answer, message templates and customer communication preferences.
- The CRM, order system and customer service platform you want to connect.

## Step-by-step WhatsApp API setup

- **Choose an integration route.** Compare direct integration by your technical team with setup through a provider, considering maintenance, support and total cost.
- **Prepare the business account.** Complete the access and verification steps Meta requires for your account. Do not assume every account has the same approval timeline.
- **Plan the number transition.** Check existing app usage and the migration or coexistence options supported by your chosen flow. Do not delete the existing account before the plan is confirmed.
- **Configure the number and business profile.** Follow the verification steps in the management interface. Check the display name, number connection and account status separately.
- **Define messaging scenarios.** Distinguish order notifications, support replies and campaigns. Check required template approvals and current messaging rules.
- **Connect your applications.** Configure event handling for incoming messages, delivery statuses and errors. Store access credentials on the server.
- **Test end to end.** Check incoming messages, automated replies, agent handover and failed delivery scenarios.

## How do you know setup is complete?

A successful API response is not enough. Verify that the message reaches the recipient, replies appear in the agent workspace and order data matches the correct customer. API connectivity and a business badge are different things; do not use the appearance of a badge as a technical acceptance test.

## Choosing between the Business App and the API

If you only need basic messaging, the existing app may meet your needs. Consider an API-based setup when you need team routing, system connections and automation. Base the decision on the work you need to complete, not just message volume.

## Which workflows can you build with Palmate?

With a [WhatsApp chatbot](/whatsapp-chatbot), you can plan FAQ responses, order lookups and team routing. Automated actions require a connection to the relevant system and permission to perform them. Start by mapping your [existing integrations](/integrations), then review the workflow during a demo using sample customer requests.

Assess platform fees, setup work and channel usage charges separately. Review Palmate's scope on the [pricing page](/pricing) and WhatsApp's product structure on [Meta's official product page](https://whatsappbusiness.com/products/business-platform/). Confirm approval timelines and account eligibility during setup.

## Frequently Asked Questions

### Do I need an intermediary provider for the WhatsApp Business API?
The integration route depends on your technical resources and the service you choose. Compare direct integration and provider-led setup in terms of support, maintenance and cost.

### Can I use my existing WhatsApp number?
This depends on how the number is currently used and the supported setup flow. Do not delete your existing account before confirming migration or coexistence eligibility.

### How many days does approval take?
It varies with the account, number and verification status. There is no fixed timeline or approval guarantee that applies to every business.

### Will my chatbot be ready once the API is connected?
No. Response sources, automation, system connections and agent handover must be configured separately.

### What should we test after setup?
Test incoming and outgoing messages, delivery status, customer matching, template use and agent handover end to end.
