I will build custom API integrations and automation with n8n
Andrei S
About this gig
Anyone can wire up ready-made nodes. The work starts where the nodes end.
An API with no connector. An OAuth flow that does not follow the pattern. A webhook that needs signature verification. A retry policy that must not charge a customer twice. That is the half most automation sellers stop at, and it is the half I build.
I deliver it as an n8n node, a small service, or both - documented, with the failure cases written down instead of discovered by your customers later.
WHAT YOU GET
- The workflow running on your own n8n, cloud or self-hosted
- Real error handling, not a node that fails silently
- Retry and idempotency logic where money is involved
- Documentation of what breaks it and what to do
APIs I HAVE INTEGRATED: ANAF e-Factura and e-Transport, Cebia, Netopia, Stripe, Fashn.ai, Supabase, Google Workspace. If yours has no connector, that is the interesting case - send me the documentation link and I will tell you honestly if it is doable.

FAQ
My API has no n8n node. Can you still do it?
That is the case I am here for. I build the custom node or a small service that speaks to it. Send me the API documentation link before ordering and I will confirm it is doable.
Do you work with Make or Zapier too?
Yes, though n8n is what I recommend when the logic is non-trivial - you own it, you self-host it, and there is no per-task pricing to work around.
Will it keep working when the API changes?
Nothing survives an API change automatically. What I build tells you loudly when something breaks, instead of failing silently - that is the difference that matters in practice.
Can you host it for me?
I can set up n8n on your own server as part of the order. I do not host it on mine - you should own the thing your business runs on.
What if money is involved?
Then idempotency and retry rules are not optional and I build them in. Tell me before ordering if any workflow touches payments, so I scope it properly.
