Technical API integration guidelines

Using TLS

TUI supports TLS Version greater than TLS 1.2.

The preferred and supported strong cipher suites are:

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 TLS_DHE_RSA_WITH_AES_128_GCM_SHA256

Some weaker suites may also be supported intermediately, but a partner should stick to those mentioned above.

Traffic Quotas

Some APIs support different partner tier levels on quota. Your partner manager will support you getting the appropriate quota set for your app subscription.

Initially we’ll assign most apps to a development access plan. This will give you access to our endpoints on the test rates of 500 calls per day and 1 call per second.

When you’ve completed your development and are ready to go live we’ll assess your estimated usage against our capacity model and assign you to one of the following production plans:

• Bronze (3 calls per second)
• Silver (6 calls per second)
• Gold (9 calls per second)
• Platinum (12 calls per second)

Some APIs may be exposed with special plans and quotas. Please refer to the documentation of each API.
