Bulk sync (ELT) from Salesforce to Snowflake

Before getting started make sure to set your Polytomic API key as an environment variable:

export POLYTOMIC_API_KEY=YOUR-API-TOKEN

This example tutorial will cover three steps:

  1. Connecting to Salesforce.
  2. Connecting to Snowflake.
  3. Loading data from Salesforce into Snowflake.

1. Create a Salesforce connection

The following request will create a Salesforce connection. The configuration for each type of connection can be found at the connection configuration page.

curl --request POST \
--url https://app.polytomic.com/api/connections \
--header "accept: application/json" \
--header "content-type: application/json" \
--header "X-Polytomic-Version: 2023-04-25" \
--header "Authorization: Bearer ${POLYTOMIC_API_KEY}" \
-d '{"name": "Salesforce Connection","type": "salesforce", "configuration": {"domain": "https://example.my.salesforce.com"}}

Since Salesforce connections uses OAuth to authenticate, we’ll need to follow the link returned in the auth_url parameter in the response

Redirection


By default, the API expects the auth_url to be opened in a new browser window. If you’d like to modify the redirect behavior, there is an optional redirect_url parameter that can be added to the request body.

2. Create an Snowflake Connection

The Snowflake instance must be network-accessible from Polytomic. For more information, see our Snowflake connection guide.

curl --request POST \
--url https://app.polytomic.com/api/connections \
--header "accept: application/json" \
--header "content-type: application/json" \
--header "X-Polytomic-Version: 2023-04-25" \
--header "Authorization: Bearer ${POLYTOMIC_API_KEY}" \
-d '{
"name": "Snowflake Connection",
"type": "snowflake",
"configuration": {
"account": "uc193736182",
"username": "user",
"password": "secret",
"dbname": "database"
}
}'

3. Create a bulk sync

This will create a bulk sync of the Account and Contact Salesforce objects into Snowflake:


Important: If the schemas parameter is omitted, all objects will be synced.

curl --request POST \
--url https://app.polytomic.com/api/bulk/syncs \
--header "accept: application/json" \
--header "content-type: application/json" \
--header "X-Polytomic-Version: 2023-04-25" \
--header "Authorization: Bearer ${POLYTOMIC_API_KEY}" \
-d '{
"name": "Salesforce Bulk Sync",
"source_connection_id": "YOUR-SALESFORCE-CONNECTION-ID",
"destination_connection_id": "YOUR-SNOWFLAKE-CONNECTION-ID",
"mode": "replicate",
"schedule": {
"frequency": "manual"
},
"destination_configuration": {
"schema": "SALESFORCE_CONNECTION"
},
"schemas": ["Account", "Contact"]
}'

Bulk sync schemas


Polytomic may take a few moments to cache source schemas after creating new connections. The message {"status":400,"message":"No schemas found. This can mean that the Polytomic has not cached any schemas yet. Please try again.","metadata":null} indicates that the schemas are not ready to be used in bulk sync configuration yet. This request is safe to retry until receiving a 2xx response.
