OTA API Registration for Channel Manager

I'm developing a hotel channel manager application and need assistance with OTA API registration. I require the following OTAs:

1. MakeMyTrip
2. Goibibo
3. Booking.com
4. Yatra
5. Travelguru
6. Cleartrip
7. Expedia
8. Trivago

Requirements:
- API documentation and access credentials for each OTA
- Registration should be done in the name of my company, no coding needed
- I have already initiated the registration process with some OTAs

Ideal Skills:
- Experience with OTA APIs
- Familiarity with hotel channel management systems
- Strong organizational skills to handle multiple registrations
