API integrations for a website

The site looks fine and leads arrive — yet the manager still copies orders into 1C and reconciles payments in Excel. API integrations are for that: payments, stock, CRM, and delivery talking to each other without a night of copy-paste.

When a connection is already worth it

• orders from the site must land in 1C or CRM immediately;
• you take card, wallet, or installment payments and “paid” never returns to the order;
• catalog stock is wrong because the warehouse lives in another system;
• the courier needs a tracking number and someone types it by hand;
• you need login via a bank, a government service, or a partner cabinet.

Five orders a week can live in a spreadsheet. Once ads send a real flow, manual transfer means errors, delays, and “we never saw your payment”.

What we usually connect

1. Payments: charge, callback, receipt, status back on the order.
2. 1C / ERP: products, prices, stock, counterparties.
3. CRM: a site lead should not die in inbox.
4. Delivery and warehouses: rate, tracking, handover status.
5. Bank and government APIs, webhooks, OAuth — when the process cannot close without them.

An integration is not “install a plugin and forget”. You need a queue, a retry on timeout, an error log, and a plan for what the manager sees if the bank is silent for ten minutes.

Timeline and budget

A typical single connection: 2–4 weeks, from $800. Included: the data map, the integration itself, failure tests, and a short handoff. More about integrations and APIs.

It costs more with several systems at once, live stock every minute, or custom 1C with no docs. Faster and cheaper: one payment plus a CRM ping.

Typical range: API integrations — 2–4 weeks, from $800. The quote comes after a brief: which systems, who owns the data, what counts as a successful sync.

Common mistakes

• trusting a demo plugin in production without refund and cancel tests;
• not naming the source of truth for price and stock;
• logs that only say “sent / not sent”, with no error body;
• tokens in a chat, no rotation, no owner;
• turning ads on the same day you switch the till.

A working start: a system list, 3–5 flows (“paid → status in 1C”), sandbox accounts, and a person who confirms the numbers match.
