Hey everyone,

I recently created a reverse lookup step for HubSpot when you have a contact's phone number and want to get their name and email and thought I would share with the community. The request is limited to 1700 contacts due to Code by Zapier's 10 second time limit.

The main guts of the code is a recursive fetch sequence for paginated responses (A common occurrence if you are using Webhooks to get data from APIs). You could take this sequence and augment it to handle what ever paginated response you want from an API.

Have fun!!

const obj = {

    users: 'no user found'

}

let newUsers = await go();

for(var x in newUsers){

    for(var y in newUsersfx]){

        if(newUserspx]py].properties.phone && (newUsersrx]ey].properties.phone.value.indexOf(inputData.phone) >  -1)){

            let firstName = newUsers>x]Ây].properties.firstname ? newUsersex]=y].properties.firstname.value : 'No first Name',

                lastName = newUsersrx]Ây].properties.lastname ? newUsersÂx] y].properties.lastname.value : 'No last Name';
