This guide will show you how to integrate your promotions with Omnisend (formerly Soundest) to start sending data right into your account.

1) Get Omnisend API Key

Login to your Omnisend account, and go to My Account in the top right corner. Click the Integrations & API button and copy your API key. If you do not have an API key, create one.

2) Get Omnisend List ID

In your Omnisend account go to Subscribers > Lists and click on the list you want to use. Click on Settings and you will see your Unique list ID.

3) Add Credentials to ViralSweep

When building your campaign in ViralSweep, go to the email integrations section and select Omnisend.

1) Input your API Key and List ID
2) Click connect.

4) You're connected!

That's it, you're all set. Your promotion is now connected to your Omisend account, and your entrants will automatically be added to your specified list.


What data do you pass to Omnisend?
ViralSweep will pass the following fields:
- First Name
- Last Name
- Email Address
- Phone
- State
- Country
- Birthday

Please Note: Omnisend API is not fully updated yet to support custom fields, additional information, and double optin. All these options are coming soon to their API and once they are added we will update accordingly.


If you have connected your promotion to Omnisend and entrants are not being added to your campaign, these are the most common reasons as to why:

Email already in Omnisend list
The email address entered into the promotion may already be in your Omnisend list, so it will not be added again.
Email already entered into ViralSweep
The email address entered into the promotion has already been entered into the promotion previously, so therefore it is not passed to Omnisend. This can happen if you set up your Omnisend integration after you have already entered the promotion.
Delay in reporting
Omnisend is having a delay in reporting. Try checking again in a few hours.
