<@1145576664366055464> On the webhook, we get the combined_cost. I presume this is the total cost of the call. Is this in USD or GBP?

Thanks for tagging me <@142232205832355840>. I'll look through relevant sources and get back to you shortly.

### Answer
 The `combined_cost` field in the webhook payload represents the total cost of the call in **cents (USD) ** [(1) ](<https://docs.retellai.com/api-references/create-phone-call>) [(2) ](<https://docs.retellai.com/api-references/create-web-call>) . To convert this to dollars, divide the value by 100 [(3) ](<https://discord.com/channels/1186424376300679209/1414243216060059750>) .

For example, if `combined_cost` is 70, that equals $0.70 USD [(1) ](<https://docs.retellai.com/api-references/create-phone-call>) [(2) ](<https://docs.retellai.com/api-references/create-web-call>) .

<@1145576664366055464> I just did some SQL to sum the cost of the combined_cost, return 10000 for example, that'll be cents. I'll have to divide by 100 to get dollars and then convert?

Thanks for the follow-up, <@142232205832355840>. I'll get back to you soon.

### Answer
 Yes, that's correct. The `combined_cost` is in **cents (USD) ** [(1) ](<https://docs.retellai.com/api-references/list-calls>) . 

If your SQL sum returns 10000, that equals **$100.00 USD** (10000 cents ÷ 100 = $100) . You would then convert that dollar amount to GBP using your preferred exchange rate.

So your workflow would be:
1. Sum `combined_cost` values (result in cents)
2. Divide by 100 to get USD
3. Convert USD to GBP using current exchange rate
