Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

New Webhook Event (Instant) on Supabase

Description:Emit new event for every `insert`, `update`, or `delete` operation in a table. This source requires user configuration using the Supabase website. More information in the README. [Also see documentation here](https://supabase.com/docs/guides/database/webhooks#creating-a-webhook)

Supabase Overview#

Supabase is a real-time backend-as-a-service that provides developers with a suite of tools to quickly build and scale their applications. It offers database storage, authentication, instant APIs, and real-time subscriptions. With the Supabase API, you can perform CRUD operations on your database, manage users, and listen to database changes in real time. When integrated with Pipedream, you can automate workflows that react to these database events, synchronize data across multiple services, or streamline user management processes.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Supabase	`supabase`	`app`	This component uses the Supabase app.
Table	`table`	`string`	The name of the table to watch for new rows
Row Identifier	`rowIdentifier`	`string`	The column name to use as the row identifier
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.

Trigger Authentication#

Supabase uses API keys for authentication. When you connect your Supabase account, Pipedream securely stores the keys so you can easily authenticate to Supabase APIs in both code and no-code steps.

Supabase provides a Service Key to get started. You can find the service_role in the API Settings page.

Overledger Overview#

The Overledger API by Quant Network allows developers to interact with multiple blockchain networks. It facilitates the creation, reading, and execution of smart contracts and transactions across different blockchains. This API simplifies the complex nature of blockchain interoperability, enabling multi-chain applications (MApps) through a single gateway.

Action Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI.

Label	Prop	Type	Description
Overledger	`overledger`	`app`	This component uses the Overledger app.
Overledger Instance	`environment`	`string`	Select a value from the drop down menu:`{ "label": "Sandbox", "value": "sandbox" }{ "label": "Overledger", "value": "overledger" }`
Location Technology	`locationTechnology`	`string`	Select a value from the drop down menu:`{ "label": "Ethereum", "value": "ethereum" }{ "label": "Substrate", "value": "substrate" }{ "label": "XRP Ledger", "value": "xrp ledger" }{ "label": "Bitcoin", "value": "bitcoin" }{ "label": "Hyperledger Fabric", "value": "hyperledger fabric" }`
Function Name	`functionName`	`string`	The name of the function to call on the smart contract.
Input Parameters	`inputParameters`	`string[]`	The input parameters for the smart contract function, provide both type and value in object format. Example: {"type":"uint256","value":"5"} or {"type":"address","value":"0x3....ed8"}
Smart Contract ID	`smartContractId`	`string`	The ID/address of the smart contract to interact with.
Output Parameters	`outputParameters`	`string[]`	Each output parameter expected, provide just the type in object format. Example - 1) function returns one uint256 value: {"type": "uint256"} or 2) function returns two address values: {"type": "address"},{"type": "address"}

Action Authentication#

Overledger uses OAuth authentication. When you connect your Overledger account, Pipedream will open a popup window where you can sign into Overledger and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Overledger API.

Pipedream requests the following authorization scopes when you connect your account:

overledger/read.scope
