I will integrate apis and connect your business systems


Level 1
About this gig
Your systems work. They just need to talk to each other.
If you need to connect your CRM, ERP, website, marketplace, payment system, communication platform, or another third-party service, I can build the integration around the way your systems actually need to exchange information.
I build API and system integrations for businesses that need reliable data flow between the tools they already use.
What I can integrate:
- REST and GraphQL APIs
- CRM and ERP systems
- Ecommerce and marketplaces
- Payment gateways
- WhatsApp and communication services
- OAuth and authentication
- Webhooks and event-driven workflows
- Databases and internal applications
- Custom third-party APIs
- Data synchronization between systems
The work can include authentication, data mapping, webhooks, error handling, retries, background jobs, and the application logic around the integration.
If you already have the systems and need them connected, or you need an API built for your own application, message me with the systems involved and what you want them to do.

FAQ
Can you connect two existing systems?
Yes. Send the names of the systems, available APIs or documentation, and what data needs to move between them.
Can you work with an API that is not well documented?
Yes. I can inspect the available documentation, authentication method, requests, responses, and existing implementation to determine the integration approach.
Can you build webhooks?
Yes. Webhooks can be used to trigger actions when an event occurs in another system.
Can you integrate payment gateways?
Yes, depending on the gateway and its API.
Can you integrate WhatsApp?
Yes, where the required WhatsApp/API access is available.
Can you synchronize data between systems?
Yes. This can include customers, products, orders, inventory, payments, or other structured data.
Can you fix an existing integration?
Yes. I can investigate API errors, authentication problems, incorrect data mapping, webhook failures, and related issues.
Will you document the integration?
Yes. Documentation can be included so your team knows what was connected and how it works.
Can you build an API for my own application?
Yes. API development can be part of a larger application or a separate project.
