Transak One Query Parameters
Note: All the query parameters marked with *(asterisk) are mandatory to send to successfully load the widget and complete the transaction.
If your smart contract will be sending some kind of receipt token like Liquid Staking Tokens (LST) back to the user wallet, you need to pass the details about that token in "cryptoCurrencyData" query parameter.
If you are not sending any token back to the user, you need not send the "cryptoCurrencyData" query parameter.
More details can be found in the Product docs here.

| apiKey * | 4fcd6904-706b-4aff-bd9d-77422813bbb7 | string | Your API key for authentication. | |
| calldata * | Example | string | The calldata/hex that needs to be passed to your smart contract in order to execute the required function successfully. The calldata should contain the method ID of the function to be executed and the values of all the parameters in that function. How to generate calldata code example Note: You need to compress the calldata and send the output as the value for this query param. Detailed explanation here. | |
| network * | Ethereum | string | A crypto network that you would allow your customers to buy NFTs on. You can get the list of supporting networks here. For ex: Ethereum | |
| estimatedGasLimit * | 34589000 | number | Gas limit that needs to be filled while executing the transaction Please refer to Ethereum Gas Docs here for more info on this for EVM compatible chains. Note: This cannot be 0 | |
| smartContractAddress * | 0x86349020e9394b2BE1b1262531B 0C3335fc32F20 | string | The address of the smart contract on which the calldata needs to be executed | |
| cryptoCurrencyData | Example | Details of the crypto user is going to receive after they do the transaction. Taking example of Aave, if you deposit USDC in a staking pool, user will receive AUSDC in return. So details about AUSDC token needs to be sent in this query parameter. | ||
| sourceTokenData * | Example | The code of the cryptocurrency that your smart contract accepts in order to execute the function. Taking above example of Aave, if you deposit USDC in a staking pool, user will receive AUSDC in return. So details about USDC token needs to be sent in this query parameter.

| walletAddress* | 0x86349020e9394b2BE1b1262531B 0C3335fc32F20 | string | The blockchain address of the user's wallet that the receipt token will be sent to. Users will be able to edit the wallet address. The wallet address needs to be valid for the blockchain network so to make sure this works you should pass cryptoCurrencyData or network. This wallet address passed here should be same as the one used to generate the calldata. As the receipt token will be sent to the address mentioned in the calldata. | |
| isTransakOne * | true | boolean | Pass this as “true”. Note: If this is passed all these query parameters should be passed compulsorily - “calldata”, “network”, “estimatedGasLimit”, “sourceTokenData”, “smartContractAddress”, "walletAddress" | |
