What LEKAB RCS API is

LEKAB RCS API lets businesses create branded, interactive conversations in customers’ messaging apps. The REST API uses JSON and provides OpenAPI/Swagger documentation and webhooks. It supports text, images, carousels, suggested replies, action buttons, and rich cards. Businesses can send using a name, logo, and colours verified by Google. If a recipient’s device or carrier does not support RCS, the API automatically switches to SMS. Delivery status, read receipts, and customer responses are available, along with engagement and conversion metrics. LEKAB says messages use verified business profiles and encrypted channels, and describes the service as built for 99.99% uptime with SLA support. The API is designed to integrate with existing customer support and CRM systems. LEKAB offers documentation, code samples, and support from its expert team. It identifies marketing, logistics, and customer service teams as users, and says it has provided business messaging solutions since 1994. RCS is widely supported on Android, while iOS support is expanding as carriers and platforms adopt it. Pricing varies by country and operator; LEKAB gives rates relative to SMS and directs prospective customers to contact sales. The company is headquartered in Stockholm, Sweden.
