Steps
Contact Planet (the company that acquired protel) to register as a technology partner and obtain access to the protel Open API sandbox environment and developer documentation
Authenticate using the credentials and authentication scheme documented in the partner portal; protel Air supports an open API framework enhanced by Planet in 2025
Use the property management API to retrieve room type definitions, rate plans, and reservation data for a connected property
Push reservation details or point-of-sale charges to the folio using write endpoints provided in the API documentation
Map your internal room and rate codes to protel-assigned identifiers retrieved from the configuration endpoints before attempting any write operations
Use the sandbox environment to complete end-to-end testing and obtain any required certification from Planet before connecting live properties
Known gotchas
protel was acquired by Planet; some older integration guides reference protel-specific endpoints and credentials that have been migrated or rebranded under Planet's platform, causing confusion for partners using pre-acquisition documentation
protel Air is a cloud PMS; on-premises protel installations use a different interface model and may not support the same REST API surface as the cloud version
Room type and rate plan configurations are highly property-specific; integrations that hardcode protel codes from one property will fail when connected to a different property with different configuration
