API integrations
Systems that talk to each other
Tejobit connects the website, shop or back office to the services the business depends on, so orders, payments, invoices and contacts flow on their own, reliably.

What is included
The most requested connections
Payments
Checkout, payment references and payment confirmations received by webhook, with the order updated automatically.
Invoicing
Invoices issued in the invoicing software from a sale, when the software provides an API.
ERP and stock
Products, prices and stock kept in sync between the ERP and the shop or back office.
CRM and email
Contacts and enquiries from the website sent to the CRM or email tool, without copying by hand.
Carriers
Shipment creation, labels and tracking of each delivery's status.
Webhooks and custom APIs
Endpoints for other systems to consume, with authentication, validation and a log of every request.
Typical cases
When it makes sense
A sale that creates manual work
Every order means issuing the invoice and updating stock by hand in another program.
Forms that never reach the CRM
Contact requests stay in the inbox and never enter the sales pipeline.
Customers asking about their order
Shipping status can reach the customer without anyone having to look it up.
Two systems that do not talk
A daily spreadsheet export that someone has to copy somewhere else.
How it works
Integrations that do not fail silently
- 01
Confirm access
Read the API documentation, confirm what is possible and get test credentials.
- 02
Design the flow
What data passes through, at what moment, and what happens when the other side does not respond.
- 03
Build and test
Development in a test environment, with error cases handled before launch.
- 04
Launch with monitoring
Automatic retries, error logging and alerts, so nothing is lost without warning.
Frequently asked questions
Before you start
Does the invoicing software need an API?
For a direct integration, yes. Without an API there are sometimes alternatives, such as file imports. Feasibility is confirmed before the proposal.
What happens if the external API is down?
Requests are queued and retried, and errors trigger an alert. Nothing is lost silently.
Where are the credentials stored?
In the server's secrets, never in the code or the browser, and with the lowest level of access the integration needs.
Who pays for the external service subscriptions?
Your business, directly to each provider. The accounts are in your name.
Two tools that should be talking to each other?
List the systems involved and what needs to pass from one to the other. The reply confirms feasibility and cost.
