Integration note

For simplicity, the examples in this guide shows you how to send requests to Spade directly. However, you will likely want to build user category personalization into client applications. Because client-side code is public and your API key is secret, you will need to proxy user category personalization requests through your backend to Spade’s servers. The merchant search guide demonstrates how to proxy requests through your backend to Spade’s API. NEVER send your API key to the client. This includes any client-side application code bundles (websites, mobile apps, etc…).

​
Fetch the default categories for your integration

The first thing you’ll likely want to do is fetch the default categories for your integration. This list contains all of the categories that Spade provides, plus any custom categories that you’ve added on an integration-wide level. 
import requests

response = requests.get("https://east.sandbox.spade.com/categories", headers={"X-Api-Key": "<Your API Key Here>"})

print(response.json())
Sending the above request returns a list containing all of Spade’s 250+ categories, plus any custom categories that you’ve added on an integration-wide level. 
[
  // Spade's default categories will show up first
  {
    "id": "001-000-000-000",
    "name": "Banking and Finance",
    "icon": "https://static.v2.spadeapi.com/categories/61897b3a5af545bab45ca1bf20498e65/light.png",
    "fullCategoryHierarchy": [
      {
        "id": "001-000-000-000",
        "name": "Banking and Finance",
        "icon": "https://static.v2.spadeapi.com/categories/61897b3a5af545bab45ca1bf20498e65/light.png"
      }
    ]
  },
  {
    "id": "001-001-000-000",
    "name": "Accounting and Bookkeeping",
    "icon": "https://static.v2.spadeapi.com/categories/61897b3a5af545bab45ca1bf20498e65/light.png",
    "fullCategoryHierarchy": [
      {
        "id": "001-000-000-000",
        "name": "Banking and Finance",
        "icon": "https://static.v2.spadeapi.com/categories/61897b3a5af545bab45ca1bf20498e65/light.png"
      },
      {
        "id": "001-001-000-000",
        "name": "Accounting and Bookkeeping",
        "icon": "https://static.v2.spadeapi.com/categories/61897b3a5af545bab45ca1bf20498e65/light.png"
      }
    ]
  },
  ...
  // Your integration's custom categories will show up next
  {
    "id": "7235be6a-669c-47f2-9ab6-cac3f3edbab9",
    "name": "Family",
    "icon": null,
    "fullCategoryHierarchy": [
      {
        "id": "7235be6a-669c-47f2-9ab6-cac3f3edbab9",
        "name": "Family",
        "icon": null
      }
    ]
  },
  {
    "id": "ba8d4e26-052a-4260-bcf4-6523469fcf48",
    "name": "Day Care",
    "icon": null,
    "fullCategoryHierarchy": [
      {
        "id": "7235be6a-669c-47f2-9ab6-cac3f3edbab9",
        "name": "Family",
        "icon": null
      },
      {
        "id": "ba8d4e26-052a-4260-bcf4-6523469fcf48",
        "name": "Day Care",
        "icon": null
      }
    ]
  }
]
Note that Spade’s categories are hierarchical, so Accounting and Bookkeeping, for instance, sits underneath the Banking and Finance category, which sits at the root level. For convenience, each serialized category includes a fullCategoryHierarchy object, which contains the full hierarchy of the category.

​
Creating a custom user category

As with default categories and custom integration-wide categories, custom user categories are hierarchical. They can sit at the root level, under Spade’s categories, under custom integration-level categories, or under other custom user-level categories. For instance, here’s how you can create a custom user category that sits at the root level: 
import requests

custom_category = {
    "name": "Kitchen Remodel 2024",
    "parentId": ""
}

response = requests.post("https://east.sandbox.spade.com/users/1234/categories", json=custom_category, headers={"X-Api-Key": "<Your API Key Here>"})

print(response.json())
Sending the above request creates a new custom user category and returns a copy of the serialized category: 
{
  "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
  "name": "Kitchen Remodel 2024",
  "icon": null,
  "fullCategoryHierarchy": [
    {
      "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
      "name": "Kitchen Remodel 2024",
      "icon": null
    }
  ]
}
Here’s how you can create a custom user category that sits under this category: 
import requests

custom_category = {
    "name": "Hardware",
    "parentId": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f"  # Replace with the ID of the category you just created
}

response = requests.post("https://east.sandbox.spade.com/users/1234/categories", json=custom_category, headers={"X-Api-Key": "<Your API Key Here>"})

print(response.json())
Sending the above request creates the new custom user category and returns a copy of the serialized category: 
{
  "id": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c",
  "name": "Hardware",
  "icon": null,
  "fullCategoryHierarchy": [
    {
      "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
      "name": "Kitchen Remodel 2024",
      "icon": null
    },
    {
      "id": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c",
      "name": "Hardware",
      "icon": null
    }
  ]
}

​
Fetching custom user categories

In order to support curated user experiences, you’ll likely want to fetch custom user categories whenever you fetch the default categories for your integration. Here’s how you can fetch custom user categories: 
response = requests.get("https://east.sandbox.spade.com/users/1234/categories", headers={"X-Api-Key": "<Your API Key Here>"})

print(response.json())
Sending the above request returns: 
[
  {
    "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
    "name": "Kitchen Remodel 2024",
    "icon": null,
    "fullCategoryHierarchy": [
      {
        "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
        "name": "Kitchen Remodel 2024",
        "icon": null
      }
    ]
  },
  {
    "id": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c",
    "name": "Hardware",
    "icon": null,
    "fullCategoryHierarchy": [
      {
        "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
        "name": "Kitchen Remodel 2024",
        "icon": null
      },
      {
        "id": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c",
        "name": "Hardware",
        "icon": null
      }
    ]
  }
]
Now that you have both the default and custom categories, you can combine them to create a list containing all of the categories that the user has access to: 
all_categories = [*categories, *user_categories]
If you’re building a UX such as a transaction feed, you can then feed all_categories to the frontend and display them as a tree, a searchable input, etc… Category search

​
Recategorizing a specific transaction for a specific user

To recategorize a specific transaction, you’ll want to update that transaction record in your internal system. For instance: 
import requests

# Update each transaction's category in your internal system.
# Note that the PATCH body will depend on your internal data schema.
requests.patch(
    "https://your.backend.com/enriched-transactions/1234",
    {
        "category": [
            {
                "id": "9fb31902-1f80-47a9-b717-cc3b1db0ad1f",
                "name": "Kitchen Remodel 2024",
                "icon": null
            },
            {
                "id": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c",
                "name": "Hardware",
                "icon": null
            }
        ]
    },
    headers=YOUR_AUTH_HEADERS,
)

​
Recategorizing all future transactions for a specific counterparty

One of the most powerful features Spade provides is the ability for users to recategorize future transactions before they take place. This feature takes advantage of Spade’s ability to consistently match transactions to stable counterparty IDs using ground truth data. Here’s how a user can recategorize future transactions for a specific counterparty: 
counterparty_category_personalization = {
    # Lowe's
    "counterpartyId": "83aa2f0a-bd1e-4613-807d-6b6f4bb39b4c",
    # Hardware
    "categoryId": "6bf9b0cd-20b5-4024-9dc2-446af3bda72c"
}

requests.put("https://east.sandbox.spade.com/users/1234/counterparty-category-personalization", json=counterparty_category_personalization, headers={"X-Api-Key": "<Your API Key Here>"})
With this personalization in place, any future transactions that take place at Lowe's for this specific user will be enriched with the custom category, which will appear in the personalization section of the enrichment as the counterparty’s industry:

    "type": "spending",

​
Deleting custom user-level categories

You can delete custom user-level categories all at once or individually. To delete all custom user-level categories, send a DELETE request to the /users/:userId/categories endpoint: 
import requests

requests.delete("https://east.sandbox.spade.com/users/1234/categories", headers={"X-Api-Key": "<Your API Key Here>"})
To delete a specific custom user-level category, send a DELETE request to the /users/:userId/categories/:id endpoint with the category’s ID: 
import requests

requests.delete("https://east.sandbox.spade.com/users/1234/categories/77f376cf-ec09-47a5-b90b-7406bb018dc9", headers={"X-Api-Key": "<Your API Key Here>"})

​
Deleting user-level counterparty category personalizations

You can delete user-level counterparty category personalizations all at once or individually. To delete all user-level counterparty category personalizations, send a DELETE request to the /users/:userId/counterparty-category-personalizations endpoint: 
import requests

requests.delete("https://east.sandbox.spade.com/users/1234/counterparty-category-personalizations", headers={"X-Api-Key": "<Your API Key Here>"})
To delete a specific user-level counterparty category personalization, send a DELETE request to the /users/:userId/counterparty-category-personalizations/:counterpartyId endpoint with the counterpartyId of the personalization you want to delete: 
import requests

requests.delete("https://east.sandbox.spade.com/users/1234/counterparty-category-personalizations/4ad9e96c-b8a4-4421-88fe-112ac23e37cc", headers={"X-Api-Key": "<Your API Key Here>"})

​
Conclusion

You’ve just learned how Spade’s category personalization endpoints can be used to create custom categories at the user-level and recategorize transactions onto those categories.
