Looks good, I just won't merge yet as I'm pending on confirmation from DevOps regarding the api.cow.fi domains. They don't seem to be active yet.
Will let you know as soon as I get an answer

Where is the URL for the API of the profile? (affiliate program)

Where is the URL for the API of the profile? (affiliate program)

I completely forgot about that, my bad.

@matextrem could you update line 56 to https://api.cow.fi/affiliate/api

And also update the respective default on lines 39 - 41?

cowswap/src/custom/api/gnosisProtocol/api.ts

Lines 30 to 56 in 2fc6c81

	process.env.REACT_APP_API_URL_STAGING_MAINNET || 'https://protocol-mainnet.dev.gnosisdev.com/api',
	[ChainId.RINKEBY]:
	process.env.REACT_APP_API_URL_STAGING_RINKEBY || 'https://protocol-rinkeby.dev.gnosisdev.com/api',
	[ChainId.XDAI]: process.env.REACT_APP_API_URL_STAGING_XDAI || 'https://protocol-xdai.dev.gnosisdev.com/api',
	}
	}
	// Production, staging, ens, ...
	return {
	[ChainId.MAINNET]: process.env.REACT_APP_API_URL_PROD_MAINNET || 'https://protocol-mainnet.gnosis.io/api',
	[ChainId.RINKEBY]: process.env.REACT_APP_API_URL_PROD_RINKEBY || 'https://protocol-rinkeby.gnosis.io/api',

	}
	}
	function getProfileUrl(): Partial<Record<ChainId, string>> {
	if (isLocal || isDev || isPr || isBarn) {
	return {
	[ChainId.MAINNET]:
	process.env.REACT_APP_PROFILE_API_URL_STAGING_MAINNET || 'https://protocol-affiliate.dev.gnosisdev.com/api',
	}

	return {
	[ChainId.MAINNET]:
	process.env.REACT_APP_PROFILE_API_URL_STAGING_MAINNET || 'https://protocol-affiliate.gnosis.io/api',

And the barn api urls wont be changing yet, could you please revert them?
