INTER-SYSTEM EXCHANGE
Connect systems.
Check exchange
We connect CRM, accounting, payment, and delivery via available API. We agree on data schemas, check repeated events and failures, and hand over documentation and exchange control procedures.

Integration is agreed exchange rules
First, we define which system is responsible for the customer, order, payment, and status. We describe fields, identifiers, and events, as well as conflict resolution rules. An HTTP response by itself does not confirm that the business operation completed correctly.
We select an available exchange method: request, webhook, queue, or scheduled upload. For retries, we verify the possibility to safely execute the action again. For payments and record creation, we separately protect against duplicates and reconcile the final status.
We test service unavailability, limits, incomplete data, and token expiration. Failed tasks receive a status and recovery path. We pass on integration, logging, and access update descriptions so that the exchange can be maintained.
- Schema of fields, identifiers, and data owners
- Available API and agreed rights
- Event signature verification and anti-duplicate protection
- Limits, timeouts, and limited retries
- Reconciliation of results and recovery instructions
Contract
It is clear what and in what format is transferred
Duplicates
Repeated event does not repeat the action
Failure
There is a status, log, and a responsible person
Reconciliation
The result is checked in the target system
Request retry requires verification
After a timeout, the operation may have already been completed. We use an operation ID, status check, or a supported idempotency key. We do not repeat a payment just because we did not receive an answer in time.
Exchange with error control
Reliability is determined by exception handling, access, and monitoring the result.
Approved data
We check mandatory fields and value conversion. Status conflict and repeated delivery are described in the rules, rather than resolved by random request order.
Managed retries
We set limits, timeouts, and the number of attempts. We consider the service recommendations about pausing; exhausted tasks are transferred to the parsing queue and we notify the responsible person.
Access and logs
Secrets are stored in an agreed, secure environment. We restrict rights, hide keys and unnecessary personal data in logs; we describe token revocation and renewal.
From documentation to a verified exchange
Before launch, we check not only a successful request but also retries, failures, and the final status.
Available interfaces
We study documentation, accounts, limits, and the test environment. We verify that the necessary operations are available.
Schema and events
We agree on fields, identifiers, and data owners. We describe events, conflicts, and criteria for a successful operation.
Integration development
We implement authorization, transformations, and agreed operations. We separate work and test accesses.
Errors and retries
We add timeouts, protection against duplicates, and a queue in the chosen volume. We limit retries and set up notifications.
Scenario verification
We test limits, unavailability, incorrect data, and re-delivery. We check final records and system statuses.
Launch and handover
We switch the environment according to the plan without real test charges. We hand over documentation, observation, and recovery instructions.
Contracts, events and exchange monitoring
We choose tools based on available protocols and operational complexity.
API and documentation
REST, GraphQL, or SOAP based on system capabilities. For a custom interface, we describe the contract; for external ones, we save examples and usage rules.
Queues and events
Task queue, status log, and protection against duplicates. We choose Redis, RabbitMQ, or relational storage based on delivery and operational requirements.
Testing and reconciliation
Test accounts, request collections, and control records. We check fields, operation status, and log limits, not just the response code.

— QUESTIONS AND ANSWERS
Everything that matters
before start
Scope of work, source materials, approval order, and launch conditions.
-
What happens if the CRM or 1C is unavailable?
Depending on the package, we save the error status or the task in the queue. Retries are limited and take into account the possibility of executing the operation safely. Once attempts are exhausted, analysis and restoration according to instructions are required. -
How is the webhook tested?
We check the signature or another method of confirmation provided by the service, data schema, and event identifier. A repeat event must not recreate a record or issue payment. The specific mechanism depends on the API. -
How are keys stored?
In an agreed-upon server environment or secrets storage, with restricted rights. We do not include keys in public code and do not output them to logs. The order of rotation, revocation, and recovery is agreed upon according to service requirements. -
Do you work with SOAP or file exchange?
Yes, if the system provides an accessible interface. We agree on format, encoding, identifiers, delivery method, and processing confirmation. Updating the source ERP may not be required, but this is checked against its limitations. -
Who pays for connected services?
Subscriptions, commissions, and licenses are paid by the account owner according to the provider's terms. We implement agreed operations and use a test environment if available. Real charges do not replace a test scenario without separate agreement.
