Questions around SDK Integration

[raxhvl]

Hi Vivek / Team,

We already have web sdk and are migrating to react native sdk.

I have gone through the documentation and Faq and have few questions around the integration:

• It seems like the order_id is optional, this is required in JS sdk. Is the understanding correct?
• If so then, do you recommend passing the amount directly in the sdk options without order_id? What are the security implications?
• Where can i get a list of all supported options?
• I guess razorpay introduced support for expo in November, do you want me to update the Readme here?
• do you still recommend to do server side validation after success call back using payment signature?
• Is the following snippet still valid, since tez got renamed as google pay?

For Expo Apps: Directly modifying info.plist is discouraged, and hence this should be added in app.json

"ios": {
    "infoPlist": {
      "LSApplicationQueriesSchemes": [
         "tez",
         "phonepe",
         "paytmmp"
      ]
    }
  }

Apologies if this is not the right forum to ask questions.
