Connect your business tools through the SAYLS API.

Use the SAYLS tenant API for supported customer resources and messaging actions. Connect an existing business application without asking staff to copy the same contact or message details manually into two systems.

The task behind the feature

When manual copying becomes an integration problem

Copying records between systems creates repetitive work.

A business may already use a website form, an internal tool or another customer system. Re-entering the same information creates delays and inconsistent records. An API gives a technical team a defined integration surface, provided the workflow uses appropriate permissions, validates data and handles failures instead of assuming every request succeeds.

One practical way to use it

Connect a supported operation to your own system.

Start withOne authenticated customer operation

01
Define the smallest useful integration
Choose a supported resource or action, such as working with contacts or sending an appropriate template. Decide which system owns each value so an update does not create a loop of conflicting changes.
02
Create a scoped access token
Use the API management workflow and grant only the required capabilities. Keep credentials on a trusted server, respect the selected plan's API access and rate limits, and do not place private tokens in browser code.
03
Test errors as well as success
Validate payloads, inspect response codes and plan safe retry behaviour. Confirm tenant context and customer permission before sending messages, particularly when a trigger can run more than once for the same business event.

Configure the path. Test it with a real task.

Use scoped credentials and test the supported endpoint and error handling before relying on the integration.

Why this is useful in practice

Less repeated data entry between your tools.

Less repeated data entry

A suitable integration can move structured information between systems when it is needed. Your team spends less time copying fields and more time checking that the underlying customer process is useful.

A defined technical boundary

Supported endpoints and token permissions make the integration more deliberate than a screen-scraping workaround. Technical staff can design around known resources and failures instead of automating clicks in a browser.

A foundation for custom workflows

Use the API where your business needs a specific connection that the standard interface does not provide. Keep the scope clear and test the complete journey before making it part of a customer promise.

Choose a useful starting point

Operations worth connecting through the API

Create supported contacts from a trusted business application.
Send a permitted template from a server-side workflow.
Read supported CRM resources for an internal tool.

Your first useful workflow

Try developer api with your team.

Use authenticated, scoped API access for supported actions. Start with one authenticated customer operation and review the result before choosing a plan.

Your business has its own questions.Tell us what you need. We'll help you find a useful starting point.

01Does the API expose every screen in the CRM?

No. Use the supported endpoints and documented capabilities. The current module includes specific contacts, statuses, sources, groups, template reads, bot reads and message-send routes rather than unrestricted access to every internal feature.

02Can API messages bypass consent or WhatsApp rules?

No. API access is a technical integration route, not an exemption from permission, approved-template requirements or Meta's messaging policies. Build those requirements into the business workflow that triggers the request.

03Is API access unlimited?

Access and call rates depend on the current plan and token configuration. Review the live plan comparison and design for rate-limit responses, temporary failures and safe retries rather than assuming unlimited throughput.
