# Tremendous
Send referral rewards automatically with Tremendous. Winners pick their own gift card or prepaid Visa from hundreds of brands.
Tremendous sends rewards for GrowSurf referral programs. When a participant unlocks a connected reward, GrowSurf sends them a Tremendous reward email, and the winner picks what they want.
You connect from inside GrowSurf. There is no Tremendous signup to do first and no API key to copy anywhere.
## Requirements
* A referral program. Tremendous is not available for affiliate programs.
* Tremendous reviews every new account before it can send anything. This usually takes a business day or two. You can set your rewards up while you wait.
* Rewards are paid from a Tremendous balance you fund yourself. Gift cards and prepaid cards cost face value with no Tremendous fee.
* Rewards can use the currencies Tremendous supports. New rewards start with your program's currency, and you can choose a different currency for the referrer and the referred friend.

**One account for your whole team**
Connecting Tremendous creates one account for your GrowSurf team. All of your programs can use the same account and balance. When you set up Tremendous on another program, you don’t need to create another account or add funds again. Just turn on Tremendous and choose the rewards you want to use.
{% endhint %}
## How It Looks to Your Winners
Your winner gets an email with the reward amount and a redemption button. The sender name is your company name.
Clicking it opens the redemption page.
From there, the winner chooses a gift card or a prepaid Virtual Visa.
## How to Set Up
{% stepper %}
{% step %}
**Start the connection**
Go to *Program Editor > 4. Options > Integrations* and open the Tremendous card. Click *Connect to Tremendous*, then choose a currency for the account: USD, EUR, or GBP.
{% endstep %}
{% step %}
**Enter your company details on Tremendous**
Fill in the company information Tremendous asks for and add a payment method. GrowSurf never sees your card. Come back to the Tremendous card and click *Refresh*.
{% endstep %}
{% step %}
**Wait for approval**
Tremendous reviews your account before you can send gift card rewards to participants. The Tremendous card shows the status of your review.
{% endstep %}
{% step %}
**Turn it on for this program**
Once you are approved, click *Turn on for this program*.
{% endstep %}
{% step %}
**Connect a reward**
Click *Connect a Reward*, pick the reward you want Tremendous to send, choose who gets the gift card, and set the amount and currency. The currency starts with your program's currency. If both the referrer and referred friend get a gift card, each can have a different amount and currency. Anytime a participant unlocks that reward, GrowSurf emails them a Tremendous reward for that amount.
{% endstep %}
{% step %}
**Add funds**
Click *Add Funds* on the Tremendous card. That opens Tremendous, where you add money and manage payment methods.
{% endstep %}
{% endstepper %}
{% hint style="info" %}
**Dynamic rewards**
Dynamic rewards let you send different amounts based on attributes of the referred friend or the referrer. For example, send `$50` when a referral signs up for your base plan and `$100` when they sign up for a higher plan.

{% endhint %}
{% hint style="danger" %}
If your Tremendous balance runs out, your winners do not get their reward emails. GrowSurf keeps the reward, and you can retry it once you add funds. See [Retrying failed rewards](#retrying-failed-rewards).
{% endhint %}
## What Winners Can Redeem
GrowSurf's Tremendous integration offers gift cards and prepaid cards from hundreds of brands. You don't choose the brand. The winner chooses which brand they want when they redeem the reward.
## Turning Tremendous Off
Click *Disconnect* on the Tremendous card to turn Tremendous off for that program only. Your Tremendous account and balance stay unchanged, and Tremendous remains connected to your other programs.
To remove GrowSurf’s access to your Tremendous account completely, disconnect GrowSurf from inside Tremendous. This removes the connection from all of your programs, so no program can send gift card rewards through Tremendous.
## Taxes
A Tremendous gift card is treated like any other reward for tax reporting. If you have Tax Forms and 1099 filing enabled for your program, GrowSurf includes the reward amount in the winner’s yearly total. The reward is held until the winner has a W-9 or W-8 on file.
## Troubleshooting
If a reward email cannot be sent, GrowSurf emails the program owner. The reason for the failure also appears on the participant's detail page and in their activity logs.
Common causes:
* Your Tremendous balance is too low to cover the reward.
* Your Tremendous account has not been approved yet.
* GrowSurf lost access to your Tremendous account. The Tremendous card shows a *Reconnect* button. Reconnecting keeps your balance, company details, and approval status.
* Dynamic reward rules are enabled, and no rule matched.
* Tremendous rejected the recipient's email address.
### Retrying failed rewards
Fix the underlying problem (typically low funds), then click *Retry Rewards* on the Tremendous card in *Program Editor > 4. Options > Integrations*. GrowSurf checks each reward against Tremendous before it resends, so a winner never gets paid twice.
## FAQ
**Do I need a Tremendous account before I start?**\
No. Click *Connect to Tremendous* in GrowSurf, and you’ll create your account as part of the setup.
**Do I have to connect again for each program?**\
No. Once your team connects its Tremendous account, other programs can use the same connection. Just turn Tremendous on with one click.
**Can I use Tremendous and Tango Card on the same program?**\
Yes. You can use either one for each reward, but you can't connect the same reward to both. Otherwise, the winner would receive the reward twice.
**Can I use Tremendous on an affiliate program?**\
No. Tremendous sends referral program rewards. For affiliate commission payouts, use [PayPal](https://docs.growsurf.com/integrations/paypal) or [Wise](https://docs.growsurf.com/integrations/wise).
**What currency are rewards sent in?**\
Choose any reward currency supported by Tremendous. Your team’s Tremendous balance can be in USD, EUR, or GBP, regardless of the currency you use for the reward. Winners choose from the gift cards available in their country. Tremendous handles the currency conversion when needed.
The reward amount can include cents when the currency supports them. For example, you can enter `10.50`.
**What happens if a winner never redeems?**\
The reward remains available until it expires, and the funds stay in your Tremendous balance. The reward email shows the expiration date.
**Does GrowSurf see my Tremendous balance?**\
Yes. GrowSurf checks your Tremendous balance so it can warn you if you may not have enough funds to send a reward. GrowSurf cannot see or access your payment methods, and it only uses your Tremendous balance to send rewards you have configured.
