What our users say


"For TUI Musement, Airbyte cut development time in half and enabled dynamic customer experiences."


“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
Begin by accessing your PostHog project. Navigate to the settings and find the API section to generate an API key. This key will allow you to programmatically access your data from PostHog. Ensure you note down the API key securely as it will be used in subsequent steps to authenticate your requests.
Determine which data you need to move from PostHog. This could be events, user data, or any other specific datasets available via the PostHog API. Review the PostHog API documentation to understand the structure and endpoints you'll need to access this data.
Use a programming language like Python or JavaScript to write a script that makes HTTP GET requests to the PostHog API using the previously generated API key. Implement pagination if necessary, as the data might be too large to retrieve in a single request. Ensure the script can handle potential API rate limits by incorporating delay or retry mechanisms.
After retrieving the data, process it to match the schema required by Convex. This might involve transforming JSON structures, formatting timestamps, or renaming fields to align with Convex's data model. Write functions within your script to automate this transformation process.
Log into your Convex account and create an API token for authentication. This token will be used to securely send data to Convex. Note the appropriate endpoint from Convex�s API documentation where the data will be uploaded.
Extend your existing script or write a new one to make HTTP POST requests to the Convex API. Use the API token generated in the previous step to authenticate these requests. Ensure the data is sent in the correct format and handle any response codes to manage errors or confirm successful uploads.
To keep the data in Convex updated, consider automating the script using cron jobs on a Linux server or Task Scheduler on Windows. Set an appropriate schedule that meets your data freshness requirements while considering API rate limits and server resources.
By following these steps, you can efficiently move data from PostHog to Convex without relying on third-party connectors or integrations, ensuring a custom and controlled data transfer process.
FAQs
What is ETL?
ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.
PostHog is an open-source Product Analytics software-as-a-service (Saas) for developers, aimed at helping software teams better understand user behavior. Offering a private cloud option to alleviate GDPR concerns, it provides the features engineers need most: it helps them automate events, understand their product usage and user data collections, tracks which features are being triggered for product events, etc.
Posthog's API gives access to a wide range of data related to user behavior and interactions with a website or application. The following are the categories of data that can be accessed through Posthog's API:
1. Events: This includes data related to user actions such as clicks, page views, and form submissions.
2. Users: This includes data related to user profiles such as email addresses, names, and user IDs.
3. Sessions: This includes data related to user sessions such as session IDs, start and end times, and session duration.
4. Funnels: This includes data related to user journeys through a website or application such as the steps they take to complete a specific task.
5. Retention: This includes data related to user retention such as the percentage of users who return to a website or application after a certain period of time.
6. Cohorts: This includes data related to user groups such as users who signed up during a specific time period or users who completed a specific action.
7. Trends: This includes data related to changes in user behavior over time such as changes in the number of page views or clicks.
What is ELT?
ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.
Difference between ETL and ELT?
ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
