Transaction processing

When Calypso receives a client deposit you will receive webhooks with transaction statuses:

• The transaction pending in the mempool (not guaranteed) - CUSTOMER_PURSE_MEM_POOL_FOUND

• Transaction under compliance check - CUSTOMER_PURSE_PENDING_COMPLIANCE

• The transaction failed compliance check and the deposit address is blocked for further deposits - CUSTOMER_PURSE_COMPLIANCE_DECLINED (transactionState: DECLINED)

• Transaction received successfully - CUSTOMER_PURSE_FUNDS_RECEIVED_FOR_PURSE (transactionState: CONFIRMED)

• After the transaction funds are credited to your company account, you will receive a webhook - CUSTOMER_PURSE_TRANSLATION_TO_ACCOUNT_COMPLETED (In the transaction information, the "translationToAccountCompleted" parameter will change to "true")

• After receiving webhooks with terminal statuses, check the transaction details and confirm the status using the method - [POST] purse-transaction
