Set up a device

Register the device. Send its serial number, its vendor and its model. List the models with GET /integration/v1/device-models.

POST /integration/v1/devices
Idempotency-Key: 0192f6c4-8a20-7d31-b4c5-d6e7f8a9b0c1

{"device_identifier": "SN-58210043", "vendor_id": "…", "model_id": "…"}

To register many devices of one model at once, use POST /integration/v1/devices/batch with a list of serials. The device starts as not_activated.

Set it up for a product at a trading. Name the trading and the acquirer, by Konsol id or by your external_ref.

PUT /integration/v1/devices/{id}/products/{product_code}

{"trading_external_ref": "HQ-T-2001", "acquirer_external_ref": "BANK-01"}

• If the product has more than one vendor, also send vendor_id. GET /integration/v1/products lists each product's vendors.
• If the trading is not enrolled in the product through that acquirer yet, this request enrolls it.
• If the device is set up at another trading, release it there first.

Every check runs before any change, so a refused request changes nothing and a repeat is safe.

Set its parameters. Find the application with GET /integration/v1/applications?product_code=…. Use the one where:

• acquirer_id is your acquirer, or null if the application serves every acquirer, and
• schema_revision is set.

Then send this device's values for it.

PUT /integration/v1/devices/{id}/applications/{application_id}/parameters

{"last_modified_at": "2026-10-22T09:30:00Z", "values": {…}}

Konsol checks the values against the application's parameter schema and delivers them to the device. Set last_modified_at to when the values changed in your system, so a delayed write cannot undo a newer one.

Issue an activation code.

POST /integration/v1/devices/{id}/activation-codes

Give the activation_code to whoever installs the terminal. The device becomes activated when the code is entered on it.
