@benedictevans If you haven’t used @pipedream yet, then you haven’t lived.

Evaluation update: @pipedream has quite literally been a dream to work with! I’m excited to leverage this tool for all the various workflows I need to write. I’m currently at 11k invocations a day from the initial workflows I’ve written in the past couple weeks.

@MBraedley
Update: I got it working properly, and it's working so well that I'm dropping IFTTT. @pipedream can do everything that IFTTT basic can, and most (if not all things) IFTTT pro can for free or at a reasonable price if you need it. I am recommending it for basically any power user.

Want quick+dirty integrations for a serverless workflow - @pipedream is my new go-to 😃
Matthew Roberts
@mattdotroberts
day 013 - finally hit node js. This is the secret sauce of taking #nocode projects that one step further. Pumped about getting deeper into @pipedream now

Yahoo Pipes is back! Kinda 😍 @pipedream

@raymondcamden
Awesome video by the @pipedream folks showing real time twitter sentiment analysis integrated with Google Sheets. This is where Pipedream *really* shines, connecting systems together in easy workflows.

I couldn't recommend @pipedream more. It's an amazing service to integrate different APIs. Much more powerful than Zapier and more user-friendly than AWS Lambda. I'm very proud to wear this t-shirt #NoCode
Jason Snow
@jyksnw
Developed a working prototype environmental sensor IoT solution with @particle Photon, @pipedream, and @MongoDB with full graphing and alerting in less than a day! All amazing technology, will def. be exploring these more.

@burgwyn you've inspired me to finally set up my own blog. I'll make sure my first blog post explains the tech behind the setup. think @obsdmd + @GatsbyJS + @pipedream.

GitHub issues should be like @linear_app for maintainers. Looking forward more integrations with GH actions or tools like @pipedream 👀

If you're a dev and not using @pipedream, you're missing out. Been using it for months, daily. FREE for devs. Plenty of integrations and good limits. Absolutely love it.

So @pipedream is pretty amazing. In 3 minutes I just made a flow which adds @rickastley's Never Gonna Give You Up to my @spotify playlist whenever a new pull request arrives in an old repo of mine.

Um, wow 🤯 @pipedream

I just used @pipedream to build a Shopify App. Wow, they make small backed tasks easy.

@_jayhack_
Very impressed with this bad boi - it reminds me of a @PalantirTech internal tool, but geared towards integrations instead of data analysis and far more customizable. Great expectations here 🚀🤩
Tree Sturgeon 🔥🚴‍♂️🌳
@philsturgeon
For context this is day 2 of a really challenging and stupid migration from Notion to @airtable with disparate/missing data. It's going better than expected and thanks to @pipedream I don't have to bother the iOS dev to add W3W.

New Email on IMAP

Description:Emit new event for each new email in a mailbox

Version:0.0.4

Key:imap-new-email

View on GitHub

IMAP Overview#

Using Pipedream's IMAP API, developers can automate interactions with their email inbox, enabling serverless workflows that perform actions based on incoming emails. This could include parsing email contents, triggering events upon receiving emails from specific senders, attaching labels, and much more. By leveraging IMAP, Pipedream can act as a bridge between your email and other services, streamlining processes that would otherwise require manual intervention.

Trigger Code#

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

emailprofilehttps://www.googleapis.com/auth/gmail.sendhttps://www.googleapis.com/auth/gmail.labels
