Auto-sync purchases, cardholder fees, cardholder fundings, and receipt images from PEX into GreenSlate, ensuring your data is clean, accurate and up to date. Map GreenSlate fields such as Project, Account, Episode, Location, etc. to PEX tags.
Note:On April 30, 2026 we will be deprecating the Legacy connector for GreenSlate.

Ways to sync transactions

You can automatically sync transactions using either the legacy app or the new app. If you use the legacy app, you don’t need to configure any settings—purchases will sync to GreenSlate automatically. However, receipts and fees will not sync to GreenSlate. To connect to the legacy app:
2
Navigate to Apps > Available
3
Locate Connector for GreenSlate.
4
Click More info > Install > Launch.
Note:To install the connector, you need to enable the following permissions: Edit business settings & apps, Manage cardholder, View card transactions. You can enable them in My Profile -> Permissions.
  • You’ll be re-directed to the Legacy tab.
5
Click Connect.
Once connected, you will see that the connection status is valid.
The second way to sync transactions to GreenSlate is by using the new app. With the new app, you can automatically sync purchases, cardholder fees, and receipt images from PEX into GreenSlate, instantly populating fields such as Project, Account, Episode, Location, and more with the correct values. Continue reading to learn how to configure the new app.
Note:
  • You can use only one app at a time; you cannot be connected to the legacy app and the new app simultaneously.
  • If you are an existing customer who used the GreenSlate connector before the new app was introduced, you will also have access to the Cards tab.
  • If you want to switch to using the new app, please ensure that the last 6 digits for any existing cards in your GreenSlate account match the GS Card # shown in your table. Otherwise, duplicate cardholders will be created in your GreenSlate account.
    1
    To update this in GreenSlate, go to Accounts Payable -> Vendors -> click “Actions” across the vendor name ->
    2
    select “View Vendor Profile In Same Tab” or “View Vendor Profile In New Tab” -> scroll down to the bottom-> click Edit ->
    3
    update the Card Last 6 digits field with GS Card # shown in your table for that particular cardholder ->
    4
    click Save.
    Make sure to update the last 6 digits for all your existing PEX cards in GreenSlate following the steps above.
Once completed, go to Connect tab to configure transaction sync to GreenSlate.

Connect PEX and GreenSlate

To connect your PEX and your GreenSlate accounts from the PEX Marketplace using the new app follow these steps:
2
Navigate to Apps > Available
3
Locate Connector for GreenSlate.
4
Click More info > Install > Launch.
Note:To install the connector, you need to enable the following permissions: Edit business settings & apps, Manage cardholder, View card transactions. You can enable them in My Profile -> Permissions.
You’ll be re-directed to a Legacy tab.
5
Click Connect.
  • You’ll see this message:
The next step is to link your GreenSlate project(s) with PEX. Please email PEX at GSSetup@pexcard.com and list the GreenSlate project(s) you want to sync PEX transactions with.
  • We will add your GreenSlate project(s) to PEX.
  • Once your GreenSlate project(s) have been added, we will send you an email so you can proceed with the configuration.

Configure Transaction Settings

On the Transaction Settings card, you can configure the Start Date and End Date. Start date:
  • Must be less than 1 year ago (if today is Aug 30, 2025 then you can not go further back than Aug 30, 2024).
  • Leave empty to default 2 months back.
  • Auto-sync will always process 2 months back.
End Date:
  • Leave empty to default to the time of sync.
  • Temporarily pick a small date range for testing and reconciliation purposes.
For PEX to know which project to sync transactions to, select a GreenSlate project. Ensure you have at least one active project to select from the list. Uncheck the checkbox to enable selection of multiple projects. Configure the following:
  • Select the envelope grouping
    • Group transactions into an envelope per cardholder, project, and company.
      • If Admins select this option, the connector creates one envelope per week, containing all purchases that are ready to sync. For example, transaction A is made on July 15, and transaction B is made on August 2. Transaction A is tagged and approved on August 3, and transaction B is tagged and approved on August 4. Both transactions will sync to the same envelope.
      • Create a single envelope per cardholder transaction.
  • Sync all transactions or only approved transactions
    • “Only sync approved transactions” means that transactions must be approved in PEX before syncing to GreenSlate.
  • Sync attachments
    • If this box is checked, purchase receipts will sync to GreenSlate.
  • Use settlement dates or purchase dates
    • Transactions sync only once settled, but you can choose either the settlement or purchase date as the posting date in GreenSlate.

Purchases

To sync purchases to GreenSlate, configure the field mapping. Purchase Field Mappings Map GreenSlate fields so the connector knows which values to use when syncing purchases to GreenSlate. Fields can be mapped to static values or PEX tags. If you choose to use PEX tags, you must create them in advance, following the logic described in the “Create PEX tags for GreenSlate” article. For example, the “Account” is one of the fields on your Purchase:
  • Mapping the “Account” field to a static value means that you can select one account out of the many presented in GreenSlate, and that value (“Advertising” in our example below) will be applied to all PEX purchases.
Note that a purchase will not be tagged with this static value. You will not see this static value on the purchase details. The static value will be used only when syncing a purchase to GreenSlate.
  • Mapping the “Account” field to a PEX tag (“Account” in our example below) means that you and your cardholders can select one of the tag values for each purchase.
For that go to the “Transactions” menu -> locate a purchase -> click on it -> select a tag value (“Office Supplies” in our example below) of the “Account” tag -> click “Save”. Note that you and your cardholders can select one of the tag values for each purchase once you finish the GreenSlate connector setup and sync tag options from GreenSlate to PEX.
When mapping to a tag, you can also specify a default “Account” value: for example, Uncategorized, as highlighted below.
Note that a purchase will not be tagged with this default value (“Uncategorized” in our example) on the purchase details. It means that if you or your cardholders forget to tag a purchase before it is synced to GreenSlate, the default value (“Uncategorized” in our example) will be applied to this purchase during the sync. If you or your cardholders do tag a purchase with the tag option from the tag chosen in the highlighted field below,
that specific purchase will be recorded against the expense account (“Transportation” in our example below) you tagged the purchase with. Tags take precedence over default values.
  • Enable the sync toggle to sync field values from GreenSlate into PEX as tag options.
For example, the values for the PEX tag “Account” (in Tag Manager) will be populated with the names of your GreenSlate accounts.

Cardholder fees

To sync cardholder fees to GreenSlate, enable the toggle Sync cardholder fees.
Fee Field Mappings Map GreenSlate fields so the connector knows which values to use when syncing fees to GreenSlate. Fields can be mapped to static values or PEX tags. If you choose to use PEX tags, you must create them in advance, following the logic described in the “Create PEX tags for GreenSlate” article. For example, the “Account” is one of the fields on your Fee:
  • Mapping the “Account” field to a static value means that you can select one account out of the many presented in GreenSlate, and that value (“Advertising” in our example below) will be applied to all PEX fees.
Note that a fee will not be tagged with this static value. You will not see this static value on the fee details. The static value will be used only when syncing a fee to GreenSlate.
  • Mapping the “Account” field to a PEX tag (“Account” in our example below) means that you and your cardholders can select one of the tag values for each fee.
For that go to the “Transactions” menu -> locate a fee -> click on it -> select a tag value (“Office Supplies” in our example below) of the “Account” tag -> click “Save”. Note that you and your cardholders can select one of the tag values for each fee once you finish the GreenSlate connector setup and sync tag options from GreenSlate to PEX.
When mapping to a tag, you can also specify a default “Account” value: for example, Uncategorized, as highlighted below.
Note that a fee will not be tagged with this default value (“Uncategorized” in our example) on the fee details. It means that if you or your cardholders forget to tag a fee before it is synced to GreenSlate, the default value (“Uncategorized” in our example) will be applied to this fee during the sync. If you or your cardholders do tag a fee with the tag option from the tag chosen in the highlighted field below,
that specific fee will be recorded against the expense account (“Transportation” in our example below) you tagged the fee with. Tags take precedence over default values.

Cardholder Fundings

To sync cardholder fundings to GreenSlate, enable the toggle Sync cardholder fundings.
Funding Field Mappings Map GreenSlate fields so the connector knows which values to use when syncing fundings to GreenSlate. The fields can only be mapped to static values. Cardholder fundings that sync to GreenSlate will credit the account selected in the “Value” column (“PEX” in our example below).
PEX fundings that sync to GreenSlate will debit the PrePaid Card Account associated with the vendor in GreenSlate.
Note:
  1. The above mappings apply to all your cardholders.
  2. Cardholder funding transactions sync into their own envelopes—one envelope per funding per cardholder.
  3. Syncing cardholder fundings is only available to PEX prepaid businesses.
Click “Save”. PEX will redirect you to the Sync tab.

Sync to GreenSlate

In the Sync tab, you can:
  1. View the last synchronization time.
  2. Manually sync transactions/tag options by clicking Execute.
  3. View Connection info.

Manual sync
Manual sync will process transactions based on the start date specified on the Execution screen, with a limit of 1 year back from today. If the start date is left empty on the Execution screen, the manual sync will process transactions only up to 2 months back from today.
Note:By default, the start date on the Execution screen is set to the first day of the current month.
