# Zapier
Optimizing your CRM has never been easier with the Shopwaive API and Zapier
{% hint style="info" %}
Don't have a Zapier account? If you prefer, you can choose to use Shopify Flow to create your automations. See [Shopify Flow](/shopify/shopify-flow.md)
{% endhint %}
## Deposits and debits
Trigger an event like customer credit top ups that deposit credits based on customer actions, such as when customers purchase a Product or SKU, or pay an invoice. For example, after customers purchase X quantities of product XYZ, then a credit deposit of Y is automatically made to the customers account.
{% hint style="info" %}
For example, after customers purchase A quantities of product B, then a credit deposit of C is automatically made to the customers account.
{% endhint %}
{% hint style="success" %}
Another example, a customer pays an invoice in the amount of Y and their credit account is automatically topped up by X\*Y, Y, or Z amount, where X is any multiplier you define, Y is the amount of the invoice paid, and Z is any amount you choose.
{% endhint %}
### Multipliers
You can also include multipliers, such that the amount of credit deposited is a multiple of the Order or Line Item subtotal that triggered the top up.
> For example, your customer purchased five units of SKU #90183749 for a subtotal of $45.10 USD. This SKU was defined in a Shopwaive Trigger with a multiplier of 10 to top up a customers credit balance.
In the example above, the customer's available credit balance is increased by $451.00 USD. If you'd like a 1:1 exchange for purchases and deposits, then use a multiplier of 1.
## Setup a trigger
There are several ways to setup Shopwaive Triggers for your store. You can use any of the three [Shopify Flow Triggers](/shopify/shopify-flow.md#triggers), the [Shopwaive API](https://api.shopwaive.com/) (development required), or setup a [Zapier](https://zapier.com/) zap no-code required. On Zapier, Shopwaive offers the actions Get available balance, Set available balance, and Increment available balance. To start an automation when a balance changes, use the **Balance change** trigger in [Shopify Flow](/shopify/shopify-flow.md#balance-change).
### With Shopify Flow
This option is no-code and takes advantage of the Shopwaive Triggers and Actions available on Shopify Flow. Make an [HTTP POST](/shopify/shopify-flow.md#http-post) to the [Shopwaive API](https://api.shopwaive.com/) to trigger a Flow, or listen to [balance change events](/shopify/shopify-flow.md#balance-change) to power a flow.
### With API or NPM package
This option requires your development team to make requests to the API or using the [@shopwaive/credit](https://www.npmjs.com/package/@shopwaive/credit) NPM package while listening or subscribing to your platform's webhook events. Send a Shopwaive API key in the `X-Shopwaive-Access-Token` header of each request: create one in the Shopwaive app under **Settings > Develop > Shopwaive API keys**. A token you already use keeps working. To learn more [contact](mailto:support@shopwaive.com) our team.
### With Zapier
This option is also no-code, however, you do need a [Zapier](https://zapier.com/) account with Premium access to Shopify events. To set up a zap that tops up a balance, start from one of the shared zaps below; each uses a Shopwaive action. When you connect Shopwaive in Zapier, use a Shopwaive API key as the access token: create one in the Shopwaive app under **Settings > Develop > Shopwaive API keys**. A token you already use keeps working.
To record redemptions in a Google Sheet, use the [Connect Google Sheets](/shopify/shopify-flow.md#connect-google-sheets) workflow in Shopify Flow.
